I am mainly interested in General Relativity and its consequences for fundamental physics. In particular, I am trying to understand black holes, their properties and possible observational signatures. Recent studies (in particular the AdS/CFT but also higher dimensional gravity in general) suggest that black holes may provide a fundamental link between classical and quantum relativity, and many new properties of black holes have been uncovered recently. This research area provides fertile ground for speculation and many new interesting ideas. Physics is also (or mainly) about experiments and observations. I am strongly engaged in another very exciting topic: gravitational wave research. Gravitational waves are ripples in spacetime and were predicted by Einstein almost a century ago, but never directly detected. With the advent of new generation gravitational wave detectors such as LIGO (http://www.ligo.caltech.edu/) or the upcoming LISA, these traditionally tiny effects of General Relativity will be a part of modern day astronomy.
