> about

I recently defended my PhD at Stanford University in Electrical Engineering, supported by a NSF Graduate Research Fellowship. I am fascinated by both light and the brain, and I leverage optics and imaging to understand mechanisms of neural information processing and cognitive control.

> research

As a member of the Deisseroth and Wetzstein labs, I am broadly interested in designing and using new tools to understand the links between animal behavior and the structural and functional connectivity of neural circuits.

> art

I like to draw; I design clothing apparel you can buy here!
I am a photographer; check out some of my work here.

> previous

In 2019 I worked on an ambitious 'moonshot' using machine learning (mostly Graph Neural Networks) as an AI@X resident (i.e. intern...) at X, Google's secretive R&D lab.

In 2014 I worked as a computational imaging engineer at Light.

I spent the summer of 2013 traveling along the northern Mediterranean, shooting rolls and rolls of black and white film. These photographs led to a solo exhibition in the Stanford SubGallery (many of which can be viewed here).

In 2012-2013 I completed a M.Sc. in Electrical Engineering at Stanford University on an IEEE Charles Legeyt Fortescue Scholarship. I studied primarily machine learning, image processing, and photography.

During the summer of 2012, I worked at Apple as part of the Panel Process and Optics team where I leveraged my background in optical physics to improve the liquid crystal display stack, resulting in this patent.

Before I happened upon imaging, photography, and neuroscience, I was most passionate about renewable (in particular, solar) energy conversion. As an undergraduate at Stanford University, majoring in Engineering Physics, I worked with Alberto Salleo and at the National Renewable Energy Laboratory, yielding two publications in the realm of improved organic semiconductors and lifetime stability of organic photovoltaics.
