I am currently a postdoctoral research fellow at Indian Institute of Science Education and Research (IISER) Mohali, India, since November 2025. I received my Ph.D. from Indian Institute of Technology Kanpur (IITK), India, in December 2025 under the supervision of Prof. Abhijit Pal. My research interests lie in Geometric Group Theory. Here is my CV.
