RACHEL LEFEVRE was born in Bloomfield Hills, MI and is a 3rd year Junior level student at Washington University in St. Louis pursuing a Bachelor of Science Degree in Architecture. During her time as an undergraduate, Rachel has had projects featured in exhibitions and publications.
Her other interests include philosophy and the intersection between philosophical inquiry
and design. Of particular interest is the question of how design can influence human decision making and support sustainable behaviors both on the macro and the micro scale.
In addition to academics, Rachel has been involved in City Faces--an organization which works with the children of Clinton Peabody Public Housing-- as a member of the community garden and Alpha Rho Chi--a professional fraternity for architecture and the allied arts--serving as the head of the fundraising committee.
In her free time, Rachel can be found in search of the best coffee around, perusing book stores, and reading existential literature.

CONCEPT: TURBULENCE EXPLORING HOW OBSTACLES AFFECT KINETIC ENERGY
Turbulence is the chaotic movement of a fluid after it encounters an obstacle. Within nature, this results in rapids, eddys and vortexes. In fluid streams, obstacles can be introduced into the system as sources of entropy. This material study focused on intervening in a stream of water in order to induce this entropy and study how this intervention could be applied outside of a stream of water, seeking to understand the results in terms of time and discrete movements which can be extended to other architectural and social conditions.

PROGRAM AND CONTEXT: SCIENTISTS DWELLINGEXPLORING THE POETICS OF RESTING AMIDST CHAOS
The dwellings program is for a scientist observing a natural phenomenon, here the flow of pollution in and out of St. Louis proper via thermal currents and wind. The building poetically situates itself on the center of the bridge and acts as an obstacle in the normal flow of pedestrians, the air itself, and the scientist -- forcing each party to react to the building and its program in a turbulent manner. The scientist observes wind both scientifically and experientially, the interior programing containing many obstacles, the most significant being the large air vents used to capture air samples and bring them into the building. Pedestrians experience and observe air flow through participating in programmatic diversion and also having the opportunity to feel wind on the exposed side of the building and be shielded from the wind on the bunkered side. On each side, tall prairie grass enhances the experience, registering the
speed, direction, and sound of the wind.

PROGRAM AND CONCEPT: TYPOLOGIESINTRODUCING TYPE TO ENHANCE OBSERVATION
Pedestrians are diverted off the bridge into two different typological experiences: bunkered and exposed. Both typologies change the pedestrians registration of wind on the site, denying and allowing the experience. On each side, tall prairie grass enhances the experience, registering the speed, direction, and sound of the
wind.

EMBEDDED STRUCTURE
Within the plan the pylon of the bridge acts as a main obstacle disturbing circulation for the Scientist. Depressing each of the spaces within the building also creates obstructions to a dwellers path within the space while simultaneously creating a division between indoor and outdoor spaces. Outdoor porches between each space allow for air intake into the system for sampling as well as for seasonal variation in circulation
depending on the desire for outdoor exposure.

CONCEPT: SHADOW GRADIENTSUNDERSTANDING HOW LAYERING AFFECTS EXPERIENCE
Using modules which notch into each other, a systematic field of gradients was created. As styrene modules aggregated, different variations of shading were produced, drastically affecting the experience of the space within. While in plan and elevation the aggregation seems chaotic, in section the form takes on an extremely regular character--showing exactly how layering of the
modules allows for the entrance of light.

PROGRAM AND CONTEXT: URBAN CHAPELEXPLORING SHADOW GRADIENTS IN AN ON-SITE CONTEXT
The site, a pre-existing park in Clayton, MO, creates its own gradation of shadows by virtue of the middle-aged trees present. Each tree contributes some degree of shading which becomes compounded when the trees clump and aggregate themselves. Through mapping these shaded conditions, a path through the site was developed to lead those on their way to the urban chapel through their own symbolic pilgrimage, through the darkness into the light.

PROGRAM AND CONCEPT: LIGHTSYSTEMATIC LAYERING, GRADIENTS, AND EXPERIENCE
The chapel itself is comprised of six modules from the initial spatial study. In the chapel the modules develop a thickness and situate themselves in the land so as to bring organic elements into the build-ing: the vertical elements become layered glass acting as light chan-nels and the horizontal components allow for indoor growth of grass and organic material. This speaks to the idea that the chapel is a continuation of the pilgrimage like experience through the site itself. Once inside the chapel, dwellers travel from the entrance--designed only to be accessed one person at a time-- to the main chapel space allowing for both individual and collective reflection.

The material study began with researching a specific plant native to South East Missouri: Spike Rush or Eliocharis Acicularis. This re-search centered around spike rushs relation to other native prairie grasses, all of which require cyclical burning. Thus, the terrarium construction centered around the idea of cyclical burning and a dynamic platform was developed with removable lids to simulate the growing, drying, and burning cycle. This concept was carried through to the actual greenhouse design.

PROGRAM AND CONTEXT: SOULARDURBAN TENSIONS AND ACCESS TO GREENSPACE
The site for the vertical green house is Soulard, Missouri--a com-munity characterized by a sharp racial and economic divide caused largely by the construction of Highway 55 through the neighbor-hood. While the highway systematically deprives the North part of the neighborhood of prosperity, it also provides a unique oppor-tunity for the introduction of equal access green-space. Thus, the greenhouse design focuses on a way to re-appropriate all of the banks along the highway to make them ecologically and socially
functional: planting prairie grass.

PROGRAM AND CONCEPT: EXTENTINVERTING HORIZONTAL EXTENSIVENESS
The use of prairie grass is central to the overall program of the building, which serves as a community education center for native prairies. Since prairie grass has such deep root systems, usually 14 feet, its extensiveness is both horizontal and vertical. This verticality is accentuated as the prairie grass runs all along the sides of the building, following the
circulation every step of the way.

CONCEPT/PRECEDENT: TURTLEEXPLORING BUOYANCY AND HYDRODYNAMICS
The aim of this project was to create a flying machine based on a series of precedents, one natural and one mechanical. A turtle was selected for the natural precedent because of its genetic characteristics which allow it to float and glide through water, similar to how a flying disc operates in the air. A simple joint was selected as the mechanical precedent. The geometric qualities of the turtles shell were married to the naturally rigid yet free moving qualities of the joint, ultimately creating a flying machine which moves dynamically through the air and explores the poetics of how systems constrain free motion.

CONCEPT: COMPRESSION AND EXPANSIONCOMPRESSING 2D LAYERS TO CREATE 3D SPACE
The process of creating a three dimensional model began by abstracting a 2D X-Ray of cancellous bone into three dimensional space by layering. Then, a model was constructed using t-splines and was subsequently 3D printed. The same construction techniques, mainly bridging between planes of space, was then applied to the parametric design strategy.

c: line of points gets copied and moved serially again
d: lines of the same length get drawn vertically from grid
e: lines get subdivided random-ly and voronoi component creates linework from random-ized points
f: voronoi component is applied to every layer of lines
g: verticies of preceding layer become start points. component selects closest vertice on next plane as end point and draws bridging line

APPROACH: GRASSHOPPER ORGANIZING SPATIAL GEOMETRY
The parametric model is based off of a simple grid arrayed diagonally through space to replicate a slice of cancellous bone. Subsequently, voronoi
was used to create planes which were then systematically bridged using a weave.
