I am a theoretical condensed matter physicist by training who enjoys working in diverse areas of physics. A few of my research interests include quantum many-body theory, physics of disordered systems, quantum computation, transport, and topological phases. Additionally, I enjoy examining interdisciplinary topics related (but not limited) to statistical physics, optics and machine learning.
