I am a DPhil student at the VGG Lab (Oxford)advised by Prof. Andrew Zisserman at the University of Oxford. I am interested in all kinds of video understanding, specially time-sensitive video understanding.

Previously, I finished my Master’s in AI at the University of Amsterdam. Along with the coursework, I did research on video understanding at the VISLab advised by Prof. dr. Cees Snoek and Dr. Makarand Tapaswi.

In the past, I’ve been a Research Fellow at Wadhwani AI where I primarily worked on estimating infant anthropometry from a monocular video. During the pandemic, I also worked on using cough as a biomarker to detect presence of CoVID-19.

Before that, I completed my Bachelor’s in Mathematics at IIT Kanpur where I worked with Dr. Piyush Rai and Dr. Swaprava Nath.
