About Me

I am a Researcher in the AI research group (AIRG) at the Lawrence Livermore National Laboratory. I work on designing ML models for temporal sequences. Recently, I have been exploring large language models (LLMs) for modeling time-sensitive healthcare data. In the past, I have also delved into deep generative models and graph-based models for sequential data mining and recommendation systems.

Previously, I was a Postdoctoral Scholar in the Paul G. Allen School of Computer Science at the University of Washington where I worked with Tim Althoff. Even before, I was a Research Scientist at IBM Research, and completed my Ph.D. from the Department of Computer Science at the Indian Institute of Technology Delhi where I worked with Srikanta Bedathur and Abir De. Even before, I received my Bachelor's in CS from the Indian Institute of Information Technology (IIIT) Jabalpur. I have also worked as an Applied Scientist-Intern at Amazon, and as an R&D-Intern at Siemens.

About Me (The real one!)

Wow! You're still reading? Since you've come all the way here, let me tell you some interesting stuff about me. I grew up entirely in Delhi (the city of Smoke 😅) but was born in Allahabad (the city of Prime Ministers 😎). Before I went on with my seemingly never-ending degree-grabbing spree, I was a dorky student at DPS Indirapuram (a Dipsite!), an even dorkier student at Cambridge School Noida, and even dorkier at the school before (got the point?).

During my amazing four years as an undergrad, I was a member of the ABU Robocon team that was placed 9th all over India (our bots played badminton!), a rhythm guitarist in the institute rock band, a member of the counseling committee (never did anything here), and organizer of many unsung fests and clubs. I have, on occasion, also been known to do something useful there such as designing sensor network protocols and as an assistant for maintaining the networking and internet infra of the entire campus.
