... working on dwarf galaxies and near-field cosmology. My Alma Mater is the University of Basel, where I studied physics and astronomy under the supervision of Prof. Bruno Binggeli. I am especially interested in the search for and characterization of dwarf galaxies in nearby galaxy groups. For that purpose I use several different optical telescopes like the Dark Energy Camera, the Very Large Telescope, the Hubble Space Telescope, and the Sloan Digital Sky Survey telescope.

Dwarf galaxies are the most abundant and most elusive type of galaxy. And more, they are thought to be the most dark matter-dominated objects in the Universe. They are also quite distinct in size, shape and mass from other galaxies, such as elliptical or spiral galaxies. The barely visible dwarf galaxies are a major puzzle to our understanding of structure formation in the Universe, described by the cosmological dark energy + cold dark matter model. The many discrepancies for dwarf galaxies between theory and observations in small-scale cosmology have now standing names like the Too-Big-Too-Fail problem, the cusp/core problem, or the planes-of-satellites problem.
Apart from being a scientist, I am an avid guitar player, my interest ranges from Jazz Manouche to Metal. Additionally, I am an enthusiastic table top player and member of the Tabletop Verein Basilisk, a club dedicated to provide a friendly and lively environment for this hobby, which involves model building, painting, and of course playing.
I also like travel and see new places. Being a scientist certainly helps coming around. When I have free time, especially during my travels I photograph, with focus on landscape and street photography.
When at home, I also like to program (i.e. this and the two previous websites), read books, play games, and write on my blog.

If you are interested in inviting me as a speaker, please write me an e-mail about the occasion. I enjoy talking in front of a crowd, be this in a school or to interested people, and of course for academics as well.
