I graduated with a Ph.D. under the supervision of Dr. Keshav Pingali in August 2021. During my Ph.D. years, I mainly worked in distributed graph analytics and associated algorithms; near the end of my Ph.D. study I focused mainly on graph neural networks.
Links from the title of a paper typically go to the "official" conference/proceedings PDF provider (if it exists) unless otherwise mentioned, while the PDF link goes to a local copy of the paper. If the official provider doesn't give public access, the paper will have a local copy you can download for non-commercial purposes.

I do have a very inactive LinkedIn that I hardly check. Other than that, I don't have a public presence on social media.
Hobbies are mostly video games (big fighting game fan) and reading. I used to watch a lot of anime (I keep up with some stuff). I've been practicing piano after years of not playing it consistently, too.
