Main Focus

I work together with Jan Steinhoff on an effective field theoretical description of the tidal dynamics during the inspiral of binary neutron star systems. Binary systems containing neutron stars exhibit features deviating from the inspiral of binary black hole systems due to the deformability of the extended matter distributions in neutron stars. My current work focuses on the development and classification of gravitoelectric terms in the effective action of neutron star tidal dynamics in terms of their multipolar excitations and spin in the post-Newtonian (PN) limit. The precise calculation of these multipolar excitations and their effect on the waveforms of NS-NS gravitational waves may be useful in understanding the precise nature of neutron stars and gravity as a whole.


Curriculum Vitae

2019-2022: Bachelor's degree in physics at ETH Zürich (BSc Physics)
2022-2024: Master's degree in physics at ETH Zürich (MSc Physics with distinction)
My master's thesis was conducted in the group for Quantum Field Theory and Strings at ETH Zürich under the supervision of Prof. Matthias Gaberdiel and Beat Nairz. My work was primarily concerned with the calculation of anomalous conformal dimensions of bosonic BPS descendants due to an exactly marginal perturbation on the conformal field theory of the symmetric product orbifold of the 4-torus in the context of the AdS3/CFT2 correspondence.
Since September 2024 I am a PhD student in the department for Astrophysical and Cosmological Relativity at the Albert Einstein Institute under the supervision of Dr. Jan Steinhoff.
