Hello! I am an LSRF Postdoctoral Fellow at Stanford University, working with Nick Haber in the Stanford Autonomous Agents Lab at the intersection of artificial intelligence, neuroscience, and psychology.
I am interested in how cellular networks in multiple regions across a brain work together to model the world. For more detail on one of my current funded projects, see here.
I earned my PhD at Stanford University in Electrical Engineering, advised by Karl Deisseroth and Gordon Wetzstein, and supported by an NSF Graduate Research Fellowship. There, I developed optical tools for recording cortex-wide neural activity and discovered a neural oscillation—strangely localized to one cortical region—that appears to underlie dissociative effects of drugs such as ketamine. For all publications, see my Google Scholar page here. You can follow me on twitter @ikauvar if you want alerts about papers I find interesting.

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