About me
|
Welcome to my homepage!
I am a postdoctoral fellow at the Leiden Observatory.
Here I work on topics such as planet formation, accretion discs,
turbulence, and supercomputing.
I finished my PhD in 2007 at Max-Planck-Institut für Astronomie in
Heidelberg.

My research focuses on computer simulations of planet formation. I am
especially interested in the dynamics of dust particles in turbulent
protoplanetary discs. This is relevant for the formation of
planetesimals and protoplanets, the first steps on the way to real
planets.
You can read more about my research interests
here.
I am a co-developer of the Pencil Code,
a high order finite difference magnetohydrodynamics code that is
highly modular and versatile.

Today's quote
|
Kent Brockmann: Senator Dole, why should people vote for you instead of
President Clinton?
Kang: It makes no difference which one of us you vote for. Either way,
your planet is doomed. DOOMED!
Kent: Well, a refreshingly frank response there from senator Bob Dole.
