I studied physics at the University of Konstanz, Germany, and at Cambridge University, UK. I got my MSc in physics (Diplomphysiker) from Konstanz in 1997 after doing a Master thesis supervised by Prof. M. Wilkens in the group of Prof. J. Mlynek. During my PhD (Dr. rer. nat.) with Prof. W. Zwerger in the group of Prof. H. Wagner at the University of Munich, Germany, I worked on nano-electro-mechanics. 

I worked on ultra-cold atoms both  with Dr. Y. Castin  in Prof. C. Cohen-Tannoudji's cold atom group at the ENS in Paris, France, (where I was a  Marie-Curie-Fellow) and in the group of  Prof. M. Holthaus at the University of Oldenburg, Germany (Habilitation, Dr. rer. nat. habil. in 2008).

Since July 2011, I have been working in the group of Prof. Simon Gardiner at Durham University, UK. I am a member of the SCR at University College, Durham ("Castle"). My research interests lie in the area of many-particle quantum physics. Currently, the focus lies on the thermal phase transition in a one-dimensional attractive Bose gas and on far-from equilibrium quantum dynamics as well as on quantum-enhanced interferometry.

Since 2007, I have been independently supervising students. I have a successful track record as principle investigator (PI) of international collaborations. Scientific publications with me as PI include quantum-enhanced interferometry [news, Phy Rev A 94, 053638 (2016)], the thermal phase transition in a one-dimensional attractive Bose gas [arXiv:1610.09070, arXiv:1610.09074] entanglement generation in binary Bose gases [Phys Rev Lett 111 100406 (2013)], periodically driven optical superlattices [Laser Phys Lett 9 160 (2012)], the emergence of many-particle quantum entanglement & mean-field chaos [Phys. Rev. Lett. 100, 140408 (2008)] and nano-electromechanics [New J Phys 7, 240 (2005)].

I have ongoing international collaborations on simulating far-from mean-field many-particle quantum dynamics and decoherence. Methods used include the effective potential approach for quantum bright solitons I co-developed [Phys Rev Lett 101, 010403 (2009)],  time-evolved-block decimation (TEBD) and piece-wise-deterministic processes (PDPs).

In 2015, I was main organiser of the JQC-Mini-Conference Non-equilibrium quantum dynamics in low dimensions. https://www.dur.ac.uk/physics/newsandevents/jqcminicon/
