Short Bio

I am an Assistant Professor of Instruction in Computer Science at Northwestern University. I received my PhD from the School of Computer Science at Carnegie Mellon University in 2021, where I was advised by Dr. Lujo Bauer and was a member of CyLab. I received a BS in Computer Science from the University of Illinois at Chicago in 2014 where I was advised in my research by Dr. Chris Kanich. I had a short stint as a Software Development Engineer (SDE) at Amazon for a year from 2014-2015.

Students

I am always interested in chatting with motivated students interested in security and privacy and relevant research as well as CS education; feel free to get in touch if this applies to you! If you are interested in working with me on research, please check this spreadsheet first to see if I am taking on new students.

I have/had the pleasure of working with the following students on research:

Personal

I have lived in several cities including Bengaluru, Chicago, Pittsburgh, and Seattle but spent much of my formative years in India.

In my free time, I love to sing (even when I'm not free), play the piano, bike, practice yoga, read novels, and watch TV/movies/anime.

I read a lot of fiction and have been trying to keep my Goodreads shelf updated here.
