About Me

I am an incoming postdoctoral fellow at Indiana University.

I received my Ph.D. in Sep 2021 from the University of Notre Dame in the Department of Computer Science & Engineering where I was advised by Dr. Tim Weninger. I am also a member of the Center for Network & Data Science (CNDS).

My research centers on the intersection of formal language theory, graph theory, and data mining. More specifically, I study graph generative models using graph grammars.

Before this, I worked on community detection in complex networks at the Social Network Analysis Research Group at Heritage Institute of Technology, Kolkata, India.

Ph.D. Defense

I will be defending my dissertation on September 3, 2021, at 315 Stinson Remick Hall from 9:30 am – 12:00 noon EDT.

Oral Candidacy Exam

I will be taking my oral candidacy exam on April 15, 2020, at Stinson-Remick Hall 315 online from 10:00 am to 12:30 pm EDT. My proposal document can be found here, the slides here, and the video here (presentation begins around the 35-minute mark).
