I am a research group leader at the Max Planck Institute for Astronomy in Heidelberg, Germany, and I work primarily on analyzing and modeling large sets of observations that trace star formation within the Milky Way. For my modeling work, I have developed Hyperion, an open-source 3-d Monte-Carlo Radiative Transfer code. To find out more, see my Research page.
As part of my research, I am an active software developer, and in particular am involved in a number of projects using Python. One of my main roles in the Scientific Python community is being a co-ordinator and core developer for the Astropy project. You can read up about this and other projects in the Software development page.
In addition to my research and software development work, I also teach Scientific programming with Python, including both workshops for researchers and a regular Python Programming for Scientists course for students at the University of Heidelberg. You can read more about these activities and access teaching materials through the Teaching page.
