Why is the universe the way it is?

Fundamental and philosophical questions like that lead me to study physics. I wanted to know more about nature and how it works.

I did my doctorate in science at the Institute for Astronomy at ETH Zurich with Marcella Carollo and with Ben Moore at the Institute for Theoretical Physics at the University of Zurich. After my doctorate, I've spent 2 years in Santa Cruz for a postdoctoral research position (Swiss National Science Foundation fellowship) at the Department for Astronomy & Astrophysics at the University of California Santa Cruz. Then I took another 3 year position as a postdoctoral researcher at the Department of Astronomy at the University of Michigan in Ann Arbor. After 5 years in the United States, I've accepted a position as Bairen research professor at the Kavli Institute for Astronomy and Astrophysics at Peking University. In 2014, I've decided to leave academia and return to my home country Switzerland.

I was mainly interested in cosmological structure formation, galaxy formation, dynamics, dark matter, dark energy, cosmology in general, black holes, N-body techniques, integrators, algorithms, data analysis methods and visualisations.
