In August 2014 I'm starting as an Assistant Professor at the Institute of Science and Technology Austria (ISTA), located in the suburbs of Vienna. The new theory group will work at the interface of atomic, molecular, optical, chemical, and condensed matter physics, in strong collaboration with European and American researchers. If you are interested in joining my research group as a PhD student, please apply to the ISTA graduate school (you are welcome to contact me first); if you are interested in working with me as a postdoc, please e-mail me directly.

At the moment, I am an independent postdoctoral fellow at the Institute for Theoretical Atomic, Molecular, and Optical Physics (ITAMP) at the Harvard Physics Department and Harvard-Smithsonian Center for Astrophysics.

I obtained my PhD degree in 2011, working in the group of Professor Bretislav Friedrich at the Fritz Haber Institute of the Max Planck Society in Berlin. Our work was mainly concerned with a theoretical treatment of molecules in electric, magnetic and radiative fields, including field-dressed molecular collisions.

My current scientific interests focus on studying complex physical phenomena using controllable quantum systems, such as ultracold atoms and molecules.

I'm particularly excited about the following research directions:

(1) Studying open quantum systems and understanding how dissipation acts at the microscopic scale – something that experimental breakthroughs in ultracold atoms recently made possible. This opens up a perspective of turning dissipation into a useful resource for quantum state preparation.

(2) Many-body physics of ultracold quantum gases: quantum simulation of phenomena taking place in "conventional" condensed matter physics, as well as engineering Hamiltonians featuring novel, unobserved phenomena.

(3) Developing techniques to manipulate atoms, molecules, and interactions between them with electromagnetic fields, and applying this knowledge to Sub. (1) and (2), as well as to practical applications, such as using cold molecules as electromagnetic field sensors.



My Curriculum Vitae: [pdf]


Apart from the research activities, I'm an associate editor of Frontiers in Physical Chemistry and Chemical Physics – a new journal established by the alliance of Frontiers and Nature Publishing Group. The Frontiers journals practice a novel peer-review system, involving interactive review by in-house referees.
