Bio

I am a Machine Learning Research Lead at Google X for a project in AI for ethology in sustainability. My team works on a range of problems, including sensing, ML for sensing and behavior, and optimal control. We collaborate with leading academic labs.

Formerly, I obtained my PhD from the Caltech Computer Vision Lab, where I was advised by Pietro Perona and collaborated with Meister Lab. My research focused on sequential decision making in brains and machines. This involved topics spanning AI and naturalistic behavior, including computer vision, machine learning / reinforcement learning, systems neuroscience, and behavior modeling and prediction.

Previous to Caltech, I worked with various organizations internationally in advancing environmental policy, including the WHO, and theoretical neuroscience, as a Loran Scholar.
