Research interests
My research combines analytic, combinatorial, probabilistic and algebraic methods to solve arithmetical problems. It belongs to the area called arithmetic combinatorics, which has intense interactions with number theory, extremal combinatorics, harmonic analysis, ergodic theory, and various topics of theoretical computer science, such as error correcting codes, pseudorandomness etc.
A few keywords:
- Higher order Fourier analysis.
- Configurations of prime numbers, Green-Tao method.
- Finite fields and polynomial rings over them.
- Sum-product estimates.
- Density of sumsets.
