I am a 2nd year Graduate Student at CS Dept. of UW-Madison.

I am part of Wision Lab where I am advised by Prof. Mohit Gupta. My research revolves around the areas of Computer Vision and Deep Learning. Currently, I am working on Visual Recognition for Single Photon Cameras.

Earlier, I worked as a Research Engineer at Visual Understanding Lab of Samsung Research, Seoul for 3 years. Before that, I completed my Undergraduate in CS from IIT Delhi where I was advised by Prof. Vinay Riberio
