Srikar Yellapragada

I am a PhD student in the Computer Science department at Stony Brook University, advised by Dimitris Samaras. My research is focused on Generative models for Computer Vision. Before this, I was a Software Engineer at Bloomberg LP, where our team built an ETL pipeline for the ingestion of third-party data.

In 2020, I obtained my Master's in Computer Science from NYU, where I worked with Kyunghyun Cho's group on Similarity of Neural Networks, and interned at IBM Watson Health.

Previously, I obtained a B.Tech in Electrical Engineering from Indian Institute of Technology, Hyderabad, where I worked with Sumohana Channappayya on Image Processing. I interned at Video Analytics Lab, IISc Bangalore.

In my free time, I enjoy playing video games and reading fantasy novels. I'm a big fan of strategy games, such as Dota 2 and Age of Empires 2.
