About Me

I am a second year PhD student in the  Department of Statistics and Data Science  at the Wharton School of the University of Pennsylvania. My broad research interests are in the fields of:

  • Causal Inference (CI): Non-parametric identification, doubly robust estimation problems.
  • Machine Learning (ML): High-dimensional statistical, reinforcement learning problems, particularly in the context of Large Language Models.
I am fortunate to be jointly advised by Professor  Eric J. Tchetgen Tchetgen  and Professor   Edgar Dobriban.

I received my Bachelors and Masters from the Indian Statistical Institute, Kolkata. My Master's Dissertation under Prof.   Bodhisattva Sen  at Columbia University, focuses on the topic of Optimal Transportation. I have also worked on shape-constrained regression problems as a Research Intern at Carnegie Mellon University under Prof.  Arun Kuchibhotla.

Beyond statistics, I enjoy playing and following chess and badminton, and solving Rubik's cubes.
