**Research:**

My main scientific interest is to understand the non-equilibrium dynamics of many-body quantum systems.

My PhD work focused on the relaxation dynamics of ultracold fermionic atoms in optical lattices under various non-equilibrium conditions. These systems show many similarities to electrons in atomic lattices and hence can be used as “quantum simulators” for condensed matter Hamiltonians. However, ultracold atoms can also behave quite differently from solid matter. As an example, we have shown that they can relax to equilibrium states at negative absolute temperatures, which has subsequently been experimentally realized by the group of Immanuel Bloch.

More recently, I also became interested in the dynamics of systems that display strong light-matter interactions. Some of these systems are currently fabricated and probed by the group of Andrew Houck at Princeton. As a theoretical physicist, I collaborate with Hakan Tureci and David Huse on this particular topic.

My further scientific interests include Monte Carlo approaches to non-equilibrium dynamics and random matrix theory.

**Current Position:**

I am currently a postdoctoral researcher with David Blei at the Institute for Data Sciences and Engineering at Columbia University.
