I currently work at IIT Roorkee as an Assistant Professor in the Data Science and Artificial Intelligence department. Previously, I worked as a Post-Doctoral Scholar at the University of Central Florida, where I was mentored by Dr. Mubarak Shah . I completed my PhD at Visual Computing Lab, CDS, Indian Institute of Science, under the supervision of Prof. Anirban Chakraborty. Prior to that, I received my M. Tech from Jawarharlal Nehru University under the guidance of Prof. R. K. Agrawal, and B.Tech from VIT University in computer science. My area of research focuses on Artificial Intelligence at the intersection of Computer Vision, Machine Learning, and Deep Learning.
Note For Students: I am looking for motivated Ph.D. and M.Tech. students with at least some experience in Deep Learning/Machine Learning/Computer Vision. UG students who are interested in research in these areas may also contact me.
