Growth and OpportunitiesECEN is experiencing an exciting period of truly unprec-edented growth. During 2005 and 2006 we will welcome seven outstanding new faculty members, including four new posi-tions, bringing our total size to 25 — the largest ever. This has allowed us to greatly enhance computer engineering and also expand into the bio area. Expect big changes in ECEN in the next few years. Three new faculty are profiled in this newsletter.

ECEN has a remarkable history of extraordinary and highly committed faculty. Among these are Dr. H. Jack Allison and Dr. Rao Yarlagadda. Dr. Allison retired from OSU in 2005 after 44 years as a faculty member in ECEN, but continued to teach through spring 2006. Dr. Yarlagadda retired from OSU in June 2006 after 40 years as a faculty member in ECEN and contin-ues to be active. Both of these distinguished men have had an enormous impact on students and on their profession during the course of their careers. The lead article tells the story of how 21 of Dr. Yarlagadda’s Ph.D. graduates returned recently to Stillwater to pay tribute to his contributions.

The US suffers from a critical shortage of scientists and engi-neers, and our competitiveness in science and technology is eroding. ECEN was recently granted a prestigious NSF Depart-ment Level Reform grant that will allow us to redefine how we develop students into engineers. Dr. Alan Cheville, the project director, provides an overview of this effort in Engineering Stu-dents for the 21st Century. This grant, funded in excess of $1M, provides a wonderful opportunity for ECEN and its students.

Our program depends on exceptional faculty, students and staff. In this issue, we profile two outstanding graduates of ECEN. In Focus on Students you’ll meet Kristoffer Lemoins, a 2005 BSEE graduate from Edmond, who recently joined the CI A in the Washington, D.C. area as an analyst. In On the Shoulders of Giants you’ll learn about Joe Campbell, a 1992 Ph.D. graduate, who has had a remarkable 27-year career with National Secu-rity Agency and, more recently, MIT Lincoln Laboratory developing speech and security technologies that are currently used worldwide.

I hope you enjoy this issue of the ECEN Newsletter. As always, it’s wonderful to hear from alumni and old friends, prospective students, and others. Your support of ECEN and its students and faculty is sincerely appreciated.

In This IssueIn This Issue

fter 40 years of exemplary teach-ing, research and mentoring in the School of Electrical and Computer Engineering — and as rumored to occur for the last 16 years — Professor Rao Yarlagadda officially hung up his spurs in June 2006. In join-ing the College of Engineering, Architecture and Technology’s

emeritus faculty, a group whose most esteemed members never really “retire,” he certainly will continue his daily trips to campus, maintaining an office and a level of contribution to the depart-ment that his wife, Marceil, and his health will allow.

A tribute suitable of Dr. Yarlagadda and the extraordinary duration of his distinguished career of service is almost inconceivable, but this past year his Ph.D. students rose to the task. Gather-ing at the ConocoPhillips OSU Alumni Center on

Sept. 23, 2005, to honor their friend and collaborator, their visit included the announcement that $15,000 had been raised to endow a fellowship in Dr. Yarlagadda’s name to support graduate study in signal processing at OSU. Making the surprise event all the more memorable, and befitting, was the number in attendance. Of the 30

people from here and abroad that Dr. Yarlagadda personally served as Ph.D. adviser over the years, 21 returned to campus to par-ticipate in the celebration, along with their spouses and children.

Operation “Occidental Symposium”The tribute to Dr. Yarlagadda was the culmination of a full year of planning and coordination, includ-ing via a website established

to allow former students and colleagues around the globe to exchange information. To maintain the surprise, veiled communications referred to the convening of the

“Occidental Symposium” at OSU. Dr. Joseph Campbell, senior member of the Technical Staff at MIT’s Lincoln Laboratory who completed his Ph.D. in 1992 under Dr. Yarlagadda, provided the inspiration for the event.

“In 2004, there was again another cycle of rumors that Dr. Yarlagadda might be retiring,” Campbell says. “I had been handed the reins of editing Digital Signal Processing Journal, the publication Dr. Yarlagadda founded with John Hershey, and thought maybe we should do a special issue inviting all of his former students to submit articles.”

“We’re still working on that, but in an e-mail mes-sage to all his former students I mentioned in pass-ing maybe we could set up some sort of scholarship fund,” Campbell says. “I included it, literally, while going through the last edit, but then Sherry Teague saw the message and went wild and spearheaded this whole scholarship effort and putting together the reception.”

Sherry Teague, whose husband Dr. Keith Teague is another of Dr. Yarlagadda’s Ph.D. students and is associate profes-sor and head of electrical and computer engineering at OSU, began the event planning by contacting all the former scholars to gauge their interest. Among the first to respond and offer assistance was Dr. Legand Burge Jr., dean of the College of Engineering, Architecture and Physical Sci-ences at Tuskegee University. Under Dr. Yarlagadda’s tute-lage, Burge in 1979 had been the second African-American to complete a Ph.D. in electrical engineering at OSU.

“I thought it was a great idea, not only to recog-nize Dr. Yarlagadda in a way that will continue in perpetuity, but also to give encouragement and provide financial assistance to graduate students in the area of signal processing,” Burge says.

Far-reaching LegacyDr. Yarlagadda’s impact on signal processing includes being the co-founding editor of Digital Signal Process-ing Journal and chairing one of the initial International Conferences on Acoustics, Speech and Signal Process-ing, but his groundbreaking contributions are not limited to the dissemination of new knowledge.

Uniting OSU faculty from electrical engineering, physics and geology, he helped improve underground explora-tion for the oil and gas industry by developing techniques for the modeling of acoustic responses in down-hole

tools. This endeavor in the de-con-volution of well log signals led to the establishment of laboratory facilities and a productive research program at OSU that enjoyed the support of a 12-member consortium of the world’s leading companies for more than two decades.

Work to improve the integrity of digital image processing involved Sandia National Laboratories. Dr. Yarlagadda’s collaboration with Dr. John Hershey, who completed his Ph.D. in 1981 and subsequently received the CEAT’s highest alumni honor, the Melvin R. Lohmann Medal, resulted in the development of the encoding technique, Naturalness Preserving Transform, or NPT.

The School of Electrical and Com-puter Engineering’s participation in the development of techniques for speech coding and recognition and data transmission and compres-sion with the National Security Agency perhaps best exemplifies Dr. Yarlagadda’s legacy at OSU.

“Lee (Burge) came to work at my old place, and none of the people there were aware of Oklahoma State,” Campbell says. “Lee was a Ph.D. so we all wanted to know where he had studied, and, then, through Lee’s con-tacts, we started a research contract with Dr. Yarlagadda to look at alter-native norms to solving the linear predication equation for speech, an area he’d done work in previously for oil and seismic exploration.”

“We thought, ‘let’s try this on speech and establish a contract with Dr. Yarlagadda and Okla-homa State,’ and before we knew it, a lot of people were getting Ph.D.’s here,” Campbell says.

The list included Rich Dean, Tina Kohler and Campbell.

“In my case, for example, I won a fellowship and the option to go anywhere I wanted for a Ph.D.,” says Campbell, who did his undergradu-ate and master’s work at, respectively, Rensselaer Polytechnic Institute and The Johns Hopkins University.

“Because of Dr. Yarlagadda, I decided I would come to OSU, and a lot of people asked, ‘why are you not going to MIT? What are you doing?’”

“I mentioned to one of the guys headed to MIT that I was going to Oklahoma State, and he said, ‘where is that?’ and I said, ‘well, it’s with Dr. Yarlagadda.’ And even he had heard of Dr. Yarlagadda,” Campbell says. “It’s really all about what an amazing person he is and why he’s attracted so many really top people to come here and encour-aged them and helped them.”

Unparalleled Respect for StudentsDuring the Occidental Symposium, Dr. Yarlagadda, his wife and children were feted with personal anec-dotes of how his deeds as a teacher, mentor and friend helped advance his students’ scholarly and profes-sional achievement. In personal testimonials by all on hand and in letters and videos sent in by the few unable to attend, they described him compiling nomination materi-als for career awards and helping secure housing and unpack U-hauls. They told of his efforts to regain the ability to do research in time and to critique dissertations following a debilitating heart valve surgery and a mild stroke. And they spoke of his encouragement to pursue greatness by applying seasoned knowledge to important tasks.

While acknowledging their collective accomplishments, they recognized

the quiet compassion and humility of their former professor and the lasting example he sets in the way of treating others. For Dr. Yarlagadda, who is given to gush only when talk-ing about his students’ success, there could not be a more perfect tribute.

“One of the things I did was recruit older graduate students, and many of them I had known for years,” says Dr. Yarlagadda. “They were profes-sionals and had degrees from top schools all over the country.”

“They wanted to come to OSU because we had the kind of Ph.D. program that allowed them to work on projects related to their jobs and the kind of people at the university who accepted them, and I guess I was a part of that because I happened to be working in their areas,” he says.

“I think almost all of my students are brighter than I, and I think they are very serious people. When you work with serious, senior people, it’s amazing how much you can accomplish,” Dr. Yarlagadda says.

“Every other lecture in classes now, I name individuals and point out what my students have done. All of them have done remarkably well.”

ne of the critical challenges for the

United States is creat-ing enough engineers

to support our economy, infrastructure, and national defense; all of which rely heavily on technol-ogy. Unfortunately, the long term outlook for meeting this challenge is dismal. While it is impossible to give a balanced view of the interdepen-dent societal, economic, and cultural factors involved in training future engineers in two pages, I would like to give a snapshot of some alarming statistics.

• The number of students obtain-ing a B.S.E.E. degree dropped 40% nationwide from 1987 to 1998. While the total number of graduates has increased slightly since 1998, the frac-tion of engineering degrees granted compared to other degrees fell 12% from 1998 to 2001.

• About half of the students who start off in engineering will graduate with an engineering degree. If you are female or a minority the odds you will complete your engineering degree falls to one in three.

• Only 13% of engineering students are women, and less than 16% are Black, Hispanic, or Native American.

• Nationally, 56% of all graduate engineering degrees are to foreign citizens.

• One decade ago the smallest feature size China’s integrated circuit indus-

try could create was five times larger than their US competition (smaller feature sizes allow more powerful chips). Today the differ-ence is less than 50%.

• 95% of today’s engi-neering students cheat at some point in col-lege, primarily to keep up with the pressure and workload. 67% will cheat more than once in a semester.

• Since 1982 the cost of a college degree has risen 220% more than inflation.

The government, National Acad-emies, and some business leaders are acutely aware of this looming crisis in the United States’ continual demand for a scientific workforce.

Several national-level panels have been formed to give advice on this need, but it is still an open question about how univer-sities can accom-

plish reform that is cost effective and sustainable.

For several years a core of dedicated faculty in ECEN have been quietly and systematically looking at the causes of these problems and exam-ining possible solutions. This work paid off this year when ECEN won a prestigious and competitive National Science Foundation award to rede-fine the process by which students become engineers. This one million dollar grant, Engineering Students for the 21st Century (ES21C), will

enable ECEN to begin the slow pro-cess of redefining how we prepare tomorrow’s engineers.

Currently, our program — as are most undergraduate programs — is built on the paradigm that covering a specific set of concepts will prepare students for a career in engineer-ing. The assumption inherent in this paradigm is that specialized informa-tion can only be found and learned at universities. Today, with the rise of the Internet, the validity of this underlying hypothesis is questionable. As pointed out several years ago in the journal Science, “Today’s produc-tion and distribution of information are undermining the university struc-ture, making it ready to collapse in slow motion once alternatives to its function become possible”. Our pro-gram, at its core, like all others, offers information that can often be found elsewhere. For example, all of MIT’s course materials are available on-line at no charge.

OSU is not tackling these issues alone. The pressing questions that all universities are struggling with are: what should replace production and distribution of information, and what

Vitals

f you’re in Washington, D.C., and you see a man wearing orange, chances are it’s Kristoffer Lemoins.

The 2005 Oklahoma State University electrical engi-neering graduate, who now works for the Central Intelligence Agency, says he proudly wears orange as much as possible to show his affiliation to OSU.

“I work with people who graduated from Stanford, Princeton, Harvard and MIT and have both master’s and Ph.D.s,” Lemoins says. “To work with such brilliant individuals and still have valuable contributions shows

the outstanding teaching and research done at Oklahoma State University.”

While a stu-dent at OSU, Lemoins took advantage of

the many opportunities available to him. He participated in research with Dr. Cheville in the Optics Laboratory and with Dr. Guoliang Fan in the VCIPL developing a MATLAB interface for his Diabetic Retinopathy research.

Aside from schoolwork and research, Lemoins served as Webmaster for the ALPHA Program and CEAT Stu-dent Services, CEAT Student Council Representative and CEAT Career Liaison, among many other activities.

Lemoins proved himself to be an outstanding campus employee as well. In April 2005, he was awarded the Stu-dent Employee of the Year Award. Lemoins continued on to compete against students from 19 other universities to win the regional Student Employee of the Year title.

“I felt extremely excited and honored when I won the award,” Lemoins says. “I immediately went and thanked the people in the two offices that nominated me, CEAT Student Services and the Division for Student Affairs.”

Lemoins says these opportunities to succeed helped him obtain his dream job as an analyst for the CIA.

“My undergraduate coursework helped build a founda-tion of electrical engineering principles, and my research helped bolster my credentials,” Lemoins says. “I was able to answer every question presented to me with some experience I had at Oklahoma State University.”

Now four months into his career with the CIA, Lem-oins analyzes national security issues, such as foreign weapons development, weapons proliferation, informa-tion warfare and emerging technologies. He will have opportunities for foreign travel and language training.

His advice to future students is to take your own initiative.

“Find out what opportunities are out there to pursue your interests,” Lemoins says.

“There’s always something out there.”

Engineering and holds informational sessions in which Professors can speak to students about undergradu-ate and graduate research that they conduct. We hope that this will give students a deeper understanding of the different fields available.

Last Semester a new faculty advi-sor for HKN was elected. Dr. James Stine accepted the invitation at the first meeting of the Fall semester. Dr. Stine spearheaded the award-ing of the Naeter Scholarships and continues to be an active part of the organization.

HKN inducted fifteen new members in the fall. The new members and professors attended the initiation banquet in which the Naeter scholar-ships and awards were given. HKN hopes to continue what it has done in the past as well as do another Gameday this semester based on

“Wheel of Fortune.”

Eric Larson President OSU HKN Omega Chapter

Eta Kappa Nu (HKN)

Eta Kappa Nu is the only Honor Society for Electrical Engineers. Eta Kappa Nu recognizes the highest academic achievements of students majoring in Electrical and Computer Engineering. Outstanding students are invited into HKN primarily from the top one fourth of the junior class and top one third of the senior class of accredited undergraduate programs.

The purpose of HKN is to further scholarship, research, and profes-

sional opportunities for all electrical engineering students. The organiza-tion aims to support the School of Electrical and Computer Engineering by assisting its members throughout their lives in becoming better profes-

sionals and better citizens. This was the goal of the founders of HKN in 1904 and has been carried on by subsequent generations within the Oklahoma State University Omega Chapter of HKN. In honor of the achievements of the Omega Chapter it is pursing placing a monument in front of Engineering South.

Simply stating these goals, however, will not be enough to achieve what HKN stands for. Last semester, HKN hosted a Professor/Student game

titled ECEN College Gameday. Students and Professors were asked “Jeopardy” style ques-tions and then asked to build giant puzzles for final Jeopar-dEE. Dr. Scheets and his team won the competition with Dr. Latino’s team being a close

second. Dr. Scheets donated his prize of free yardwork to Kameoka Trail. HKN members and initiates gathered this semester in cleaning the trail.

HKN continues to offer free tutoring for almost all courses in Electrical

Institute of Electrical and Electronics Engineers (IEEE)

Through the OSU student chapter of the Institute of Electrical and Electronics Engi-neers, or IEEE, students have the opportunity to learn more about the profession, receive information about job opportunities, and gain much needed social skills and leadership abili-ties. Students network with other students, faculty members, and company representa-tives through social functions and monthly meetings.

We started out the year with a very successful Fall Picnic where both students and faculty enjoyed hamburgers, mingling, frisbee, and volleyball. This was a chance for the two groups to improve relationship by mixing informally outside the classroom.

Representatives from National Instruments, Nomadics, and Nextel/Sprint spoke at the monthly meetings. In addi-tion to introducing representatives from a variety of com-panies, one of the goals of IEEE was to also focus on the influence of Electrical Engineering and its technology in the world today. The Nextel presenter spoke on personal experiences repairing the Nextel/Sprint network in New Orleans during the Katrina disaster relief.

We wrapped up the year with a ‘Study Break’ during pre-finals week. Students took a break from projects and studying with games and coffee from a local coffeehouse known as The Third Place.

In the spring, speakers representing companies from dif-ferent aspects of the Electrical Engineering discipline will continue to share each month, but the much anticipated event of the semester is always the Spring Banquet. Stu-dents have a chance to interact personally with compa-nies to learn more about them, network, and hand out résumés while enjoying a nice dinner. Companies have a chance to promote themselves by donating door prizes and last year the coveted prize was a 40 GB Apple iPod.

Another small project that IEEE completed this year was to create a new message board, so students who pass through the department can see what our activities are. The old message board, originally built by Greg Blackburn (MS. ’80), had not been replaced in many years. The stu-dents of the Oklahoma state chapter of IEEE continue to improve our professional society. By bringing in speakers from across the profession, developing better relations between students and department faculty, and supporting the lifelong bonds of friendship developed during col-lege, IEEE has made itself a vital and dynamic part of the department.

We encourage any alumni who wish to become involved to contact any of the IEEE officers. Although our member-ship changes every year, please contact officers by visiting our website (ieee.okstate.edu). The website also contains information concerning the organization and its upcoming events.

From 1979 to 1990, Campbell was a member of NSA’s Narrowband Secure Voice Technology research group. He and his teammates developed the first DSP-chip soft-ware modem and LPC-10e, which enhanced the Federal Standard 1015 voice coder and improved US and NATO secure voice communications systems. He was the prin-cipal investigator and led the US Government’s speech coding team in developing the CELP voice coder, which became Federal Standard 1016 and is the foundation of digital cellular and voice over the Internet (VoIP) tele-phony systems.

From 1991 to 1998, Dr. Campbell was a senior scientist in NSA’s Biometric Technology research group, where he led voice verification research. From 1994 to 1998, Joe chaired the Biometric Consortium, the federal government’s focal point for research, development, test, evaluation, and application of biometric-based personal identification and verification technology.

“Voice biometrics incorporates biological and behavioral traits,” Campbell said. “The natural signals produced by a voice give it interesting advantages where you want to use it so that the speaker doesn’t know or realize they’re being recognized.”

“The combined biological and behavioral elements of the analysis also make speaker recognition a very attractive form of authentication for security and access-control purposes.”

n describing his prolific, 27-year career in devel-oping speech processing technologies, Joseph P. Campbell acknowledges that until recently, he wouldn’t have been able to tell you much about the first two decades. Now a Senior Member of the Technical Staff at the Massachusetts Institute

of Technology’s (MIT) Lincoln Laboratory in the Information Systems Technology Group, he previ-ously served at the National Security Agency (NSA).

“That was a very interesting time, and we did a lot of pioneering work,” Campbell said. “Recent changes in security at my former employer allow me to discuss for the first time some of that work.”

From 1998 to 2001, he led the Acoustics Section of NSA’s Speech Research branch, conducting and coordinating research on and evaluation of speaker recognition, lan-guage identification, gender identification, and speech activity detection methods.

“The ability to recognize different speakers has all sorts of growing, large scale applica-tions,” Campbell said. “Access control was very popular and done at Texas Instruments many years ago, but, more recently, we’ve seen it employed in everything from law enforcement to the Home Shopping Net-work to analyze thousands of calls a day ….”

Campbell said that utilizing speaker recognition in moni-toring unfamiliar voices presents a more daunting chal-lenge for researchers

“Our ability to recognize different voices stems form our familiarity with the speakers, including high-level distinc-tive phrases and common knowledge,” he said. “We use all of this familiar knowledge when it comes to recogniz-ing a talker and you don’t have that when it comes to unfamiliar speakers, so the majority of our challenge in using speech processing forensically is recognizing the unfamiliar.”

“This high-level-based speaker recognition work that has been going on since about 1999,” he said. “It’s a challenge that requires us to fuse together lots of information, seemingly effortlessly, and it’s extremely difficult to do properly with machines.”

In the past few years at MIT Lincoln Laboratory, Camp-bell’s group has also been working on machine translation, including text-to-text and speech-to-speech translation.

Campbell received the B.S. degree in electrical engineer-ing from Rensselaer Polytechnic Institute in 1979, the M.S. degree in electrical engineering from The Johns Hopkins University in 1986, and the Ph.D. degree in electrical engi-neering from Oklahoma State University in 1992.

Campbell was an Associate Editor of the IEEE Transac-tions on Speech and Audio Processing from 1991 to 1999 .He taught Speech Processing at The Johns Hopkins University from 1991 to 2001. He is a former IEEE Signal

Processing Society Distinguished Lecturer and member of the IEEE Signal Processing Society’s Board of Governors. Campbell is currently a Coeditor of Digital Signal Process-ing journal, a member of Sigma Xi, a Co-chair of the Inter-national Speech Communication Association’s Speaker and Language Characterization Special Interest Group (ISCA SpLC SIG), a full member of the ISCA and the Acoustical Society of America, and a Fellow of the IEEE.

he development of a versatile laboratory, with the ability to study power systems, power electronics, and energy conversion,

which can be used to complement the theory taught in class, is an important investment in US and global welfare in the years to come. We have completed many of these laboratory goals by build-ing a brand-new state-of-the-art laboratory at OSU Tulsa, and more recently by significantly upgrading the

lab at OSU in Stillwater. The equipment available in these labs acquires and displays data in real time so that stu-dents can immediately see the effects of changes in their circuit or voltages, currents, or mechanical loads, rather than the more traditional approach of 1) turn knob, 2) write some numbers down, 3) do laborious calculations later, and 4) hopefully figure out what these numbers mean just before the lab report is due. Because of the digital acquisition, processing and real-time display, stu-dents can see instantaneously the effect a change in circuit parameters and/or topology through real-time phasor dia-grams and current and voltage harmonics, as well as cur-

rent, voltage, real and reactive power, etc. The display of this data is done using National Instruments’ LAB-VIEW software; the data is acquired by NI boards after signal conditioning and isolation have been done by our own in-house design. Processing and display of information collected by the hardware can be changed at will simply by writing a new LABVIEW program.

We hope that we can further increase the versatility of the lab by inclusion of a flex-ible power electronics module, which would allow us to perform experiments in machine drives, flexible AC transmission systems (FACTs) in addition to experiments we can already perform. Our concept of such a unified power electronics laboratory is discussed in a paper in a special section of the IEEE Transactions on Power Systems (Feb 2004) focusing on power engineering education. The lab to date can support courses in energy conversion and power systems, as well as some senior design proj-ects. The addition of a flexible power electronics module would support several courses in power electronics and increase the ability to complement courses in power systems. We are in the pro-cess of building individual pieces of such a module through senior design projects.

These upgrades were conducted by Dr. Thomas W. Gedra, who designed much of the circuitry and wrote the LABVIEW programs. Over the years, many students helped to build the lab, and while all their contributions are greatly appreciated, two students played crucial roles in the most recent labs’ construction or upgrades: Dr. Seungwon An (Ph.D. from OSU ECEN), project manager of the Tulsa lab construction, and Mr. Qamar H. Arsalan (pictured with Dr. Gedra above), assistant project manager for the Tulsa lab, project manager of the upgraded Stillwater lab, and Ph.D. can-didate in ECEN.

Coming Down the Pipe Engineering Students for the 21st Century continued from page 3

is an engineering degree if it isn’t mastery of some set of knowledge? OSU’s new administration has chosen to follow most other universities by: 1) building research infrastructure to produce more information (and the potentially lucrative intellectual prop-erty it creates), 2) embracing technol-ogy to help distribute information more efficiently, and 3) continually updating the curriculum to keep up with the exponential growth of information produced by universities. Whether this model is sustainable is questionable since it creates built-in positive feedback that demands ever-increasing investment.

Engineering Students for the 21st Century addresses some of the dif-ficulties inherent to the third point, updating the curriculum. Curriculum updates are typically attempted through removing “legacy mate-rial”; knowledge that is no longer useful or current. ECEN’s attempts to update the program this way have generally never been entirely successful. We have learned from experience that removing legacy material is nearly impossible since there is no universally accepted way to identify what constitutes legacy material. What knowledge is useful depends entirely on the context in which it is used rather than any intrinsic merit of the material itself. Since over 40% of newly minted BSEE’s take a job outside electrical engineering, and only 50% work in an area closely related to what they studied, it is impossible to foresee what students need to know.

If removing legacy material will not help us teach future engineers, what

can ECEN do? The key thesis of ES21C is that all knowledge must be learned in context. Without practic-ing being an engineer, it is difficult to train a student to become an engi-neer. Engineering Students for the 21st Century, changes our degree program from the old, knowledge-based paradigm (acquiring a set of concepts) to one that is develop-ment-based (emphasizing students’ development). Students at all levels will be taught how engineers tackle design problems, how to monitor their own development, and how to find, evaluate, and communicate information. This approach redefines the role of both faculty and the uni-versity, and represents a fundamental shift in the focus of an engineering degree. During the next three years ten courses will be tagged as devel-opment courses and focus more on teaching students how to solve engi-neering problems than any specific set of concepts. If you are interested in the specifics of how Engineering Students for the 21st Century will redefine an engineering degree, keep an eye on our web site and future newsletters.

Will we succeed? The odds are against it. Machiavelli once com-mented that changing institutions is the hardest thing a man can attempt because everyone knows exactly what they have to lose while no-one can judge accurately what they have to gain. Two decades of investment in engineering education has yielded little change, and OSU is both conservative and tradition-bound. Help from our alumni is needed to support change as well as to forge long-term partnerships with indus-try that will support the facilities and equipment needed by our students. Ultimately, the question ‘will we suc-ceed?’ is not important; the attempt

must be made since the problems that loom in our country’s future are too great not to try. The oppor-tunity is enormous. As Tennyson said in the closing of Ulysses:

It may be that gulfs will wash us down … [but]

Tho’ much is taken, much abides; and tho’

We are not now that strength which in old day Moved earth and heaven; that which we are, we are:

One equal temper of heroic hearts,

Made weak by time and fate, but strong in will

To strive, to seek, to find, and not to yield.
