I am a condensed matter theorist working on strongly correlated quantum systems, with a focus on the interplay of strong interactions and quantum entanglement, leading to new emergent phenomena both in thermal equilibrium and in non-equilibrium quantum systems. Some of my recent research interests include: thermalization, quantum hydrodynamics, non-equilibrium steady states, quantum entanglement, tensor networks, many-body localization, disordered systems, driven quantum systems,  topological phases of matter and topological phase transitions.

For more details, please have a look at my research interests and publications. If you are interested in working with me, see my contact information below.


I am an Assistant Professor in the Physics Department at the University of Massachusetts, Amherst. Prior to this, I was a Postdoctoral Fellow at Lawrence Berkeley National laboratory (2013-2017), working in the Condensed Matter Theory Center at the University of California, Berkeley in Joel Moore’s group.  I obtained my PhD at IPhT (CEA, Saclay) and LPTENS (ENS, Paris) under the supervision of Hubert Saleur and Jesper Jacobsen.
