Research Interests

My research interest lies in representation theory and is motivated by the connection between algebraic groups and combinatorics. My work delves into the intricate interplay among the maximal torus, the Borel groups acting on Schubert and spherical varieties and their associated combinatorial structures. Lately I’ve been investigating the shellability of symmetric spaces via their Bruhat orders posets. Also, I am keenly interested in topics related to algebraic coding theory.
