Research Groups

In 2008-2017 I was a research scientist in the Department of Astronomy and (2010-2017) a member of the Center for Spacetime Symmetries in the Physics Department, both at Indiana University in Bloomington, Indiana, USA.

In 2007-2008 I was a lecturer in the General Relativity group in the School of Mathematics at The University of Southampton, England.

In 2001-2007 I was a postdoc in the numerical relativity group at the Albert-Einstein-Institut (Max Planck Institut für Gravitationsphysik), in Potsdam, Germany. My stay at the AEI was partially funded by the Alexander von Humboldt Foundation and partially by the AEI. My main research focus was on the simulation of, and finding apparent horizons in, binary black hole systems.

In 1998-2001 I was a postdoc in Professor Peter C. Aichelburg's research group at The University of Vienna, studying of self-similarity and critical phenomena for an SU(2) sigma field coupled to gravity. This system has a continuous parameter, such that the self-similarity transitions between discrete and continuous self-similarity as the parameter is varied.

In 1992-1993 was a research associate and postdoc in the Center for Relativity at the University of Texas at Austin.
