Hi there, I’m Dr. Raphael Marschall, a planetary physicist. Welcome to my website!


I am a physicist working as a post-doctoral researcher at the Southwest Research Institute in Boulder, CO, USA. Previously I’ve worked at the International Space Science Institute (ISSI) in Bern after completing of my PhD at the University of Bern in the Planetary Imaging Group.


My primary scientific interest is in small bodies in our solar system. In my work, I study and analyse data acquired by interplanetary spacecraft. In particular, I’ve focussed on the data sets collected by the European Space Agency’s (ESA) spacecraft Rosetta to comet 67P/Churyumov–Gerasimenko. Within that work, I have built parts of a comprehensive 3D modelling pipeline to study the emission of gas and dust from cometary nuclei and their subsequent dynamics within the inner comae.


My Research

My research focus has been studying the dust and gas emission from comets in particular of comet 67P/Churyumov-Gerasimeko. Currently I’m also involved in research of the Jupiter Trojans and NASA’s Lucy mission. Here you will find more information about my research and a list of peer reviewed papers.
