About

Shrisudhan Govindarajan

PhD Student @ SFU, Burnaby

I am currently a Ph.D. student in GRuVi Lab, SFU, advised by Prof. Andrea Tagliasacchi. I've had the pleasure of working with Prof. Kaushik Mitra from IIT Madras, on self-supervised light field synthesis. I've also had the chance to worked with Pawan Baheti from Qualcomm, India as a part of Qualcomm Innovation Fellowship, 2021-22.

My main research interest lies at the intersection of Computer vision and Computer Graphics. I am recently drawn towards the latest research works in NeRF and 3DGS, and their intersection for 3D scene representation. I am mainly interested in working towards developing generalizable 3D scene representations.
