About my Research 
In simple words
The main focus of my research is on the characteristic oscillation modes of compact objects, such as neutron stars and black holes.
Different compact objects have different spectra and similar to atom spectroscopy or seismic studies of Earth, one can potentially learn a lot about the objects from the knowledge and correct interpretation of their spectrum.
While theoretical studies of gravitational wave emission have been investigated for a long time, observational access to gravitational waves is a recent and revolutionary progress in physics. My specific line of research is on the question about how the knowledge of characteristic oscillation modes can be used to reconstruct properties of the source, thus to solve the inverse problem. With further improvements of gravitational wave observatories, the spectroscopy of compact objects is in reach soon. Recently I have been working on using the shadow of black holes to test general relativity and studied rotating neutron stars from their characteristic oscillations. An explanation of my research and the one of the Max Planck Institute for Gravitational Physics can also be found in this podcast.
A little bit more technical
In most of my works I have studied the quasi-normal mode spectrum of compact objects, including neutron stars [6], models of ultra compact alternatives [1,2,5], and black hole space-times beyond general relativity [8]. These works are all within perturbation theory. In order to address the inverse quasi-normal mode problem, I have explored semi-analytic methods, such as WKB, to constrain the perturbation potentials and case dependent also parts of the metric and other properties of the objects. Furthermore I have conducted research projects on gravitational wave parameter estimation [3], Hawking radiation [7] and black hole area quantization [9,15]. Currently I am extending the inverse spectrum methods to address more complex systems and work on gravitational wave parameter estimation using Bayesian analysis [10,16,18]. I have also been working on using the shadow of the supermassive black holes to test strong-field general relativity [11,14]. Recent work includes Bayesian inference to relate neutron star oscillations with their parameters [13,17,23]. After moving to the Albert Einstein Institute, I started working on analyzing the black hole ringdown overtone problem [21] and advanced techniques for the computation of quasi-normal [19,20,22].
