Short Bio
2020 – present Assistant Professor of Physics and Astronomy at Texas Tech University,
USA
2018 – 2020 Postdoctoral Scholar at the Kavli Institute for Theoretical Physics, USA
2015 – 2018 Postdoctoral Scholar at the California Institute of Technology, USA
2011 – 2015 Graduate student at the Radboud University Nijmegen, the Netherlands
2007 – 2011 Research assistant at the Dr. Remeis observatory Bamberg, Germany
Research Interests
My research interest revolves around late stellar binary evolution, strong gravitational wave sources, supernova Ia progenitors and time-domain surveys. My research goal is to observationally constrain the population of the most compact binaries using optical time-domain data and compare their properties and distributions to theoretical predictions. My techniques focus on the use of 'Big Data' and survey science to discover and characterize rare events and populations of different stellar types in large databases. I am member of the LISA consortium, the BlackGEM and ZTF science collaborations and I have been PI for more than 50 nights of observing time at world-class observatories used for my studies.
My enthusiasm in astronomy started already very early in my study. Already as a 2nd year undergraduate student I joined the group of Prof. Dr. Ulrich Heber at the Remeis observatory in Bamberg. As ERASMUS student I spent 3 months at Armagh observatory, Northern Ireland to work on an abundance analysis of extreme helium stars which I continued as Master thesis. In May 2011 I started my doctorate at the Department of Astrophysics at the Radboud University Nijmegen on ultracompact AMCVn type binaries supervised by Prof. Dr. Paul Groot which I finished successfully in July 2015. Before joining Texas Tech University, I did Postdoctoral training at the California Institute of Technology (2015 - 2018) and the Kavli Institute for Theoretical at UC Santa Barbara (2018 - 2020).
