Cambridge Science Festival poster One of my images of cells could be seen up and down Massachusetts Avenue in Cambridge for several years, before the laminated posters bleached and disintegrated.
Notebook sketch My experience with MIT's oral qualifying exam in materials science and engineering.
Controlled-exposure microchip A controlled-exposure technology is described here in an adapted excerpt from my 2006 MEng thesis.

Optical profilometry image of buckled thin film

I've collected a variety of thin film patterns.

MicroCHIPS logo

From 2001 to 2005 I worked for MicroCHIPS, Inc., a Boston-area bioMEMS company. This extended abstract describes the state of the technology in 2003.

3DMEMS platform

One of my areas of research at the University of Maryland was 3-D microfabrication.

Thermal actuator

The other was electrothermal actuation.
