Research Interests
My research is centered around the connections between particle physics and cosmology. In particular, I work on the phenomenology of dark matter, possible production mechanisms as well as astrophysical and experimental probes. I am also interested in resolving the question why there is more matter than anti-matter in our Universe.

Keywords: particle physics — cosmology connection, dark matter, physics of the early Universe, big-bang nucleosynthesis, physics beyond the Standard Model

Curriculum Vitae
I currently work on my PhD thesis in the DESY Theory Group under the supervision of Kai Schmidt-Hoberg. Before moving to Hamburg, I obtained my Bachelor's and Master's degrees in physics from the University of Frankfurt, Germany, in 2015 and 2017 with theses under the supervision of Owe Philipsen.
