Hi!
I am an faculty at the Center for Security, Theory & Algorithms Research (CSTAR) and the Machine Learning Lab at IIIT Hyderabad, broadly interested in theoretical and applied computer science problems.
I did my Phd thesis on Computational Complexity theory (at TIFR Mumbai) and continues to have interest in Complexity theory, Combinatorics and Graph theory. Later I went on to do research (at IIIT Hyderabad) in Deep Learning, specifically Model Compression techniques and Semantic Segmentation for Autonomous Navigation. A summary of my research can be found here.
