Research Interests
I am an experimental condensed matter physicist with a strong interest in light-matter interactions. I develop and utilize time-resolved and nonlinear optical techniques in both the terahertz (THz) and optical frequency regimes to study and control properties of materials broadly known as ''quantum materials’’, which are topological and correlated materials. In this class of matter, collective phases and properties defy a classical description, often leading to an exotically rich range of emergent phenomena. My research interests include but are not limited to, topological insulators, semimetals and superconductor, quantum antiferromagnets and spintronics, 2D magnets and quantum spin liquids.
