My ResearchI am currently Research Professor at the UW Astronomy Department. My main research field is cosmic structure formation. Using computer simulations I try to understand how Galaxies, Super Massive Black Holes and Galaxy Clusters formed out of Dark matter, Baryons, Dark Energy ...and a lot of physics. It is a rapidly changing, fascinating field, that rewards a vivid imagination, attention to details and collaborative work. Plus, you get to play with big computers and Galaxies are pretty to look at. What's not to like? Here is a list of topics and relative papers that I am interested in these days:
- The Substructure Problem
- High Redshift Galaxies
- JWST: Aka the New Space Telescope
- AGORA: Simulating Disk Galaxies
- Cosmology & The Cold Dark Matter Paradigm
My Long Term Collaborators
I am part of an international collaboration, the: N-Body Shop..
CDM heats up. (Nature, in press Spring 2014)

The Formation of a Realistic Disk Galaxy (DEC 2012)
In collaboration with Prof. Alyson Brooks and Prof. Susan Kassin (STScI) we simulated one of the most sophisticated models of a Milky Way Galaxy. This animation was used for a NASA press release and has more than 300k hits on YouTube. Link.…
