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.

Activities

CMU School of Computer Science Musical (2015 - 2020): I was in the 2015 CMU SCS Musical production of The Drowsy Chaperone, the 2016 production of Lucky Stiff, and the 2019 production of Dirty Rotten Scoundrels. I also participated in the SCS Musical Revue (Spring 2017, Fall 2017, Fall 2019, Spring 2020).

CyLab Gaming Committee Head (2015 - 2017): I organized bi-weekly board game nights for CyLab at 7pm on the CIC 4th floor (reference pivot: October 13th). I have also planned various other activities such as CyLab bike rides.

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, eat desserts, and watch TV/movies/anime.

I read a lot of fiction and have been trying to keep my Goodreads shelf updated here. Also, check out my Japan blog here!
