I am the Founding Engineer at Optica Industries,
where I lead ML and Perception. We are backed by Addition, Lightspeed, & Neo.
Previously, I worked on Humanoids at Persona AI & researched Video Understanding at Sieve Data to power Petabyte-scale video datasets for Frontier AI Labs.
I am interested in Inverse Problems and JEPAs, advised by Vivek Boominathan, Randall Balesteiero, & Ashok Veeraraghavan.
Before this, I've worked on Chip Design, Nano Neuro-electronics, and Energy at the MIT Media Lab, Ajayan Group, and IIT Guwahati.
Here are some things I believe. I also like to write about things that interest me.
Research
