About Me
I was an electrical engineer in the field of MEMS (Micro ElectroMechanical Systems) and chip-scale photonics. I was drawn to studies where I could play with the function of shape and material. I am now switching to a career where the design of shape and material can be more directly experienced. I am invested in architecture that connects to community, to the environment, and to relevancy in the world today.

Solution #1: Pop-Up Rings
Us rings are poppped off the substrate as they are undercut. This keeps th ing the time it takes for the 3D shape to develop.

Variations in ring number, ring width, and gap width were studied.
This method works well for larger hemispheres (400-2000μm diameters), but how can we decrease the size?

Public Space Precedent ¡ Transformation ¡ Site One of the transformed essence models was used as the form for a civic engagement center, to be placed on a site investigated and reported on by a group of students studying urban planning. The site shown is a donating site within a TDR zone, and since developable air rights had been sold to neighboring high-rise buildings, the bordering residential buildings were visually dominated and cut off from the nearby river. For this reason, I designed my building to sit mostly below ground, and to use sections of glass that not only bring light into the underground space, but also maintain visibility from the residential zone to the adjacent green. Access is maintained by deleting portions of the extruded shape in section.

The final model explores my own idea of interlocked behavior: Spatial definitions mediated by the mechanism of architectural geometry. These spaces explore the idea of surfaces that are not singularly defined as floor, or wall, or ceiling, but shift between these states through the mediation of the defined geometry. In this sense, the structure itself becomes the mechanism that interlocks these definitions, and the surface becomes a universally applicable paradigm to define the functionality of space.
