Hello there! Let's begin with a quote,
"What I cannot create, I do not understand" - Richard Feynman

I am a PhD student studying computer vision at the University of Wisconsin-Madison . My interests revolve around constrained and stochastic optimization problems and their applications to Computer Vision. I am very fortunate to be advised by Prof. Vikas Singh .

I am also lucky to have been associated with the following wonderful mentors: Julian Yarkony (Verisk), Sathya Ravi (UIC), Vibhav Vineet (MSR), Rudra Chakraborty (Amazon).

Prior to my graduate studies, I received my bachelor's degree in Electrical Engineering from IIT Kanpur where I was advised by Prof. Laxmidhar Behera.
