I'm a CSE PhD student at UCSD with Tzu-Mao Li and Ravi Ramamoorthi, working on all sorts of things in (differentiable) rendering, generative AI and 3D vision. I've been fortunate to work with several wonderful folks at Adobe Research, Iliyan Georgiev, Michaël Gharbi and Matt Fisher and NVIDIA Research, Thomas Müller, Merlin Nimier-David and Alex Keller.

Previously, I did my MS in ECE at Carnegie Mellon University working on computational imaging with Aswin Sankaranarayanan, and my BTech in ECE at IIT Guwahati.
