About Me

I am a final year student of the Master of Statistics (M.Stat) program at the Indian Statistical Institute (ISI), Kolkata. During the summer of 2024, I was a Visiting Research Scholar in the Department of Statistics and Data Science at Carnegie Mellon University, where I was mentored by Aaditya Ramdas. Prior to that, in the summer of 2023, I worked in the Machine Learning cohort at the Big Data Summer Institute, School of Public Health, University of Michigan. I earned my Bachelor of Statistics (B.Stat) degree from ISI Kolkata in 2023. During the summer of 2022, I was a Research Fellow at the Indian Institute of Science (IISc), Bangalore, where I was mentored by Manjunath Krishnapur. Over the course of my undergraduate and master’s studies, I also had worked with Professors Subhajit Dutta and Nikhil R. Pal. My research interests span a broad spectrum within statistics and machine learning. I am passionate about working on algorithms, theory, and applications in these fields that address practical challenges.
