Debmalya Bandyopadhyay

I am a PhD student in Pure Mathematics at the University of Birmingham, United Kingdom, supervised by Dr. Allan Lo. In October 2026, I will be a Postdoctoral Fellow with Dr. Daniel Horsley at Monash University, Melbourne. My main research interests are in Extremal and Probabilistic Combinatorics.

Previously, I completed an Integrated BS-MS in Mathematical Sciences from the Indian Institute of Science Education and Research (IISER) Kolkata.
