VISIONTo produce globally competent biotechnologists with a commitment to serve the society.
MISSIONTo promote research and development in the field of biotechnology and establish a Centre
of Excellence for product development.
PROGRAM EDUCATIONAL OBJECTIVES Our graduates have the ability to apply knowledge across the disciplines and in emerging areas of
biotechnology for higher studies, research, employability and product development. Our graduates have the communication skills, sense of responsibility to protect the environment
and ethical conduct towards their profession and commitment to serve the society. Our graduates possess academic excellence, managerial skills, leadership qualities and understand
the need for lifelong learning for a successful professional career.
PROGRAM OUTCOMESProgram outcomes are narrower statements that describe what students are expected to know
and be able to do by the time of graduation. These relate to the skills, knowledge, and behavior thatstudents acquire in their matriculation through the program. Engineering programs must demonstratethat their students attain the following outcomes: An ability to apply knowledge of mathematics, science, and engineering An ability to design and conduct experiments, as well as to analyze and interpret data An ability to design a system, component, or process to meet desired needs within realistic
constraints such as economic, environmental, social, political, ethical, health and safety,manufactur-ability, and sustainability.
An ability to function on multidisciplinary teams An ability to identify, formulate, and solve engineering problems
An understanding of professional and ethical responsibility An ability to communicate effectively The broad education necessary to understand the impact of engineering solutions in a global,
economic, environmental, and societal context An recognition of the need for, and an ability to engage in life-long learning A knowledge of contemporary issues and An ability to use the techniques, skills, and modern engineering tools necessary for engineering
practice. An ability to carry out research in different areas of Biotechnology resulting in patents, journal
publications and product development.
