### Research interests

**Areas of specialization and related research interests:**

The area of my specialization is Harmonic Analysis, especially the following topics:

1. Singular integrals and function classes in the multi-parameter setting;

2. Singular integrals, multilinear singular integrals with non-smooth kernels, and function classes associated with operators;
