Pulkit Kumar

I am persuing my PhD at University of Maryland, College Park, advised by Abhinav Shrivastava. My current research interests are in video understanding, mainly action understanding. I am also interested in pushing the boundries of open world vision.

Before starting my graduate studies, I was a senior data scientist at ParallelDots, where I worked in computer vision and speech recognition with its applications in market research. I was also a research associate under Dr. Anubha Gupta at IIIT, Delhi where I explored the applications of computer vision in medical imaging diagnostics.

I did my bachelors at Netaji Subhas Institute of Technology, New Delhi in Information Technology, where I was advised by Dr. Anand Gupta in my Bachelor Thesis Project. During my junior and senior year, I split my time studying at NSIT and interning with the amazing team at ParallelDots.
