Very few Moore graphs , Some basic concepts in finite geometries – old stuff from my internship with Bhaskar Bagchi.

Grid reduction of polynomials, Combinatorial Nullstellensätze and Chevalley-Warning theorems

Symmetric polynomials and finite fields

The cap set problem using the polynomial method – notes on the result by Ellenberg-Gijswijt based on the techniques of Croot-Lev-Pach which is discussed here.
