|Delving into Python: a fitting line that “boings” into place (with a digression on spring-mass-dampers, vibration and control theory, and integral transforms), a touch-switch-activated random Steely Dan player on a Raspberry Pi, and a four-item kitchen timer on a tablet.|
|I’ve collected a variety of thin film patterns and the fantastic variety of terms used to describe them.|
|Prototyping demonstrations: polished brass letters that magnetically trigger LEDs.|
|The origins and motifs of the chemomechanics logo.|
|A brief survey of the Peter-and-Paul paper-folding trick, and my own version.|
|My doctoral research on the chemomechanics of biological cells (thesis, 7MB) was performed in the Van Vliet Group in the Department of Materials Science and Engineering at MIT under co-advisors Prof. Krystyn Van Vliet and Prof. Robert Langer.|
|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.|
|My experience with MIT's oral qualifying exam in materials science and engineering.|
|Mapping our round-the-world trip programmatically using different global projections.|
|A controlled-exposure technology is described here in an adapted excerpt from my 2006 MEng thesis.|
|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. We published this report of preclinical testing in Nature Biotechnology in 2006.
In 2012, the common stock underwent a 100-to-1 reverse split, making most employees' shares worthless; in 2018, as the company essentially went out of business, the very new CEO sought for herself a Section 280G payment—also known as a golden parachute payment—of $1.2 million.
|One of my areas of research at the University of Maryland was 3-D microfabrication.|
|The other was electrothermal actuation. In this summary, I derive an equation for estimating the first-order time constant of a microfabricated suspended beam, which we published in the Journal of Micromechanics and Microengineering.|
|My thoughts on philosophy, logic and teaching are well represented here.|
