I'm Sam Geen. I'm a theoretical astrophysicist using cutting-edge supercomputer simulations combined with pen and paper models to understand how massive stars shape their environment through nebulae and shape the formation of everything from gas clouds to whole galaxies.

I am currently a postdoc at the University of Heidelberg in Germany, working at the Insitute for Theoretical Astrophysics. I've previously worked at the University of Oxford in the UK and the Lyon Observatory and CEA Saclay in France.

You can find a list of my publications as free PDFs here.
