Hi! I am Anubhab, a second-year DPhil Student interested in Extremal, Additive and Probabilistic Combinatorics, as well as Discrete Geometry. More specifically, I have worked on extremal and counting questions arising from Additive Combinatorics (sum-free, product-free sets) and Discrete Geometry (circle-free, line-free sets) using techniques such as hypercontractivity, hypergraph containers and non-Abelian Fourier Analysis.
My supervisors are Peter Keevash (Oxford) and Rob Morris (IMPA).
