About me
I'm a Postdoctoral Researcher at the Albert Einstein Center for Fundamental Physics in Bern as an SNF Postdoc.Mobility Fellow. My research focuses in particular on foundational questions in gravity theory and its overlap to the quantum world, along with predictions for the future space-born gravitational wave detector LISA.

A selection:
Foundations of Gravitational Physics
Gravity is special because the energy carried by a gravitational field will itself source an additional gravitational field: it is inherently non-linear. This results in the prediction that every gravitational wave will leave its traces in the form of permanent scars within the fabric of spacetime. This is the gravitational wave memory effect!
Predictions for the Next Generation of GW Detectors
The LISA mission led by ESA will be constructed of three spacecrafts connected through lasers that will allow measuring the deformations of space-time due to the passage of gravitational waves in an entirely new regime. Excitingly, the gravitational wave memory effect is expected to be finally measured by LISA!
Cosmology
Cosmology is the study of the origin, structure, and development of the entire universe. While the current standard model is based on General Relativity, inconsistencies within the determination of key cosmological observables could indicate the first experimental sign for the need of a theory beyond.
