About Me

I am a third-year computer Science PhD student at The University of Maryland, College Park working with Prof. Soheil Feizi. I am a recipient of the Kulkarni Fellowship 2023. My research interest lies in the area of Security and Privacy in AI. Recently, I have been working on the hardness of AI-content detection. I also like to think about AI privacy problems that span differential privacy, machine unlearning, unlearnable datasets, and privacy attacks.

I received the prestigious Director’s Silver Medal and my Bachelor’s degree in Computer Science & Engineering in 2020 from IIT Gandhinagar. I was a Junior Research Fellow with Prof. Anirban Dasgupta at IIT Gandhinagar, India in the Data Science Lab. Previously, I had interned at Caltech, Microsoft Research India, and IISc.

Personal Stuff

I come from the beautiful town Kollam in Kerala. In my free time, I love to sing and play the ukulele and guitar. Check out my YouTube and Instagram pages for my musical covers. I also love playing badminton, soccer, ultimate frisbee, and cricket.
