Research Interests

The main goal of condensed matter research is to study emergent low temperature phases in correlated and disordered materials. A comprehensive understanding of strongly correlated materials requires several complementary analytical and numerical methods. My research interests are focused on developing such theoretical tools for addressing emergent quantum phases and quantum phase transitions in strongly correlated and disordered materials, with an emphasis on underlying topological properties. This is motivated by the recent progress in quantum material science, which is allowing us to study interplay between strong electronic interactions and spin orbit coupling in iridium based oxides, Heusler and heavy fermion compounds, where phase diagrams can display a confluence of competing orders, topological properties and exotic quantum critical phenomena. I enjoy working on abstract theoretical problems and close collaborations with different experimental groups.
