I'm an astrophysicist. After 10 years as a postdoc, I am now "Senior Science and Communication Coordinator" at the Cosmic Dawn Center, University of Copenhagen.My tasks include communicating our science to the public, organizing workshops, maintaining our website, coordinating sundry scientific and administrative activities, as well as performing my own research in astrophysics, mainly in galaxies and their formation. My research is mainly numerical/theoretical (as opposed to observational/experimental). That is, I develop computer programs that simulate the physics of the Universe, and use these programs to interpret and predict real observations.In particular, I model galaxies numerically and perform radiative transfer simulations of Lyman α radiation in the interstellar medium of these galaxies.
