Ishit Mehta

About

I am a PhD student at UC San Diego, where I work on computer graphics and vision with Ravi Ramamoorthi and Manmohan Chandraker. Previously, I was at IIIT Hyderabad studying computer vision and computational photography. I have spent time at Microsoft Research, Adobe Research, Meta Reality Labs and Google. My research is partly supported by the Qualcomm Innovation Fellowship.
