Biography

I grew up in Germany, started college in the US at UC Davis and finished college in Germany where I worked on the electronics of X-ray space missions. Then I did my masters in the US at Penn State, where I first worked on galaxy evolution and the build-up of metals. For my PhD I switched advisors to work on the connection between theory and observations in galaxy surveys, particularly the Hobby-Eberly Telescope Dark Energy eXperiment (HETDEX).

Education

  • UC Davis
  • Eberhard-Karls Universität Tübingen
  • Penn State

Research Interests

I am interested in maximally exploiting the cosmological information contained in galaxy surveys. I am also interested in the possibility of forming black holes from self-interacting dark matter after recombination.

Selected Awards
