I am interested in the approximate analytical description of binary
compact objects in general relativity and its application to
gravitational wave astronomy. More specifically, I am interested in the
inclusion of higher multipoles of the compact objects, such as spin or
quadrupole, into the post-Newtonian, post-Minkowskian, and small
mass-ratio approximations. The quadrupole is composed of spin-induced
deformation and tidal deformation. The latter can be understood as an
excitation of the oscillation modes of the single objects due to tidal forces.
line of research also raised my interest in single compact objects, in
particular black holes and neutron stars. I am interested in their
stationary solutions in general relativity and alternative theories, perturbations of these solutions, and oscillations modes.
am also interested in various computational methods for approximations
for binary systems, namely the canonical formalisms of general
relativity, the multipolar post-Minkowskian formalism, and effective field theories.Publications

I studied physics at the Friedrich-Schiller-Universität Jena from 2001
to 2006. My diploma thesis on supersymmetric lattice field theories was
supervised by Prof. Andreas Wipf. Still at the university of Jena, I
started my PhD on the canonical formulation of spin in general
relativity under supervision of Prof. Gerhard Schäfer. After I received
my PhD in 2010, I went to the Instituto Superior Técnico in Lisbon as a postdoc. I started my second postdoc at the AEI in 2014. Since September 2019, I have been leading a research group on analytic, perturbative solutions to the two-body problem in gravity, taking also advantage of recent methods developed in high-energy particle physics.
