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.
