I am currently a PhD student in the numerical relativity group at the Albert Einstein Institute (AEI) as a member of the International Max Planck Research School on Gravitational Wave Astronomy. At present, I am interested in magnetospheres of black holes, neutron stars and binary systems composed thereof, both from the analytical and numerical point of view. I perform MHD simulations of these systems in full general relativity. Such simulations are a powerful means to unravel one day the precise physical processes and mechanisms that power gamma ray bursts — tremendously energetic astrophysical events numerously observed by astronomers.

Further research interests include:

  • Asteroseismology of solar-like stars and the Sun
  • Excitation mechanisms of stellar oscillations in solar-like stars
  • Stellar structure and evolution models for non-relativistic stars
  • Stellar model optimization based on asteroseismic data
  • Solar irradiance modelling and impact on Earth’s climate


Here are links to my publications since 2010 from ADS and Spires.

Diploma thesis: Excitation of stellar oscillations by gravitational waves (PDF, 200 p., 4.1 MB)

About me:

Before I joined the numerical relativity group at the AEI in April 2012, I have been working in the field of asteroseismology on excitation mechanisms of stellar oscillations in solar-like stars at the Kiepenheuer Institute for Solar Physics (KIS). I studied Physics at the University of Freiburg and at Imperial College London. In 2011 I received the German diploma degree in physics with honors. In my Diploma Thesis project carried out at KIS under the supervision of Dr. Markus Roth and Prof. Oskar von der Lühe I developed a method to detect a stochastic background of gravitational waves (of astrophysical and cosmological origin) in measurements of stellar oscillations (cf. my publications). Such an experiment has the capability to compete with present and future gravitational wave antennas in the mHz and muHz region. As an undergraduate I have been working on total and spectral irradiance reconstruction models with Dr. Yvonne Unruh at Imperial College London. These modeling approaches are essential in assessing the Sun’s contribution to the variability in the Earth’s climate system.

Besides, I love singing, playing the organ and the piano (solo and in ensembles). I have joined numerous choirs; currently, I’m a member of Campus Cantabile Potsdam. Furthermore, I regularly perform a variety of sports, such as jogging, (mountain) biking, playing soccer, alpine hiking and skiing. Finally, I am a member of the German Amateur Radio Club (DARC) and of the German Physical Society (DPG).
