Summary of Interests
Strongly correlated electron systems. Frustrated magnetism. Orbital physics. Competing phases and emergent order in systems with strong spin-orbit coupling.

About My Work

My research is in the field of theoretical condensed matter physics. My goal is to understand properties of materials from fundamental microscopic basis. I am particularly interested in all kinds of phenomena observed in magnetic materials. In my work, I focus on developing and analyzing microscopic models of electronic systems with strong interplay between charge, spin, and orbital degrees of freedom, and geometric frustration. This is an exciting area of condensed matter physics with rapidly evolving fundamental concepts, discoveries of materials with intriguingly novel behaviors and high promise for useful applications.
