My name is Raphael Marschall and I am a planetary physicist working as a post-doctoral researcher at the Laboratoire J.-L. Lagrange of the Observatoire de la Côte d’Azur in Nice (France). Previously I’ve worked at the Southwest Research Institute in Boulder (CO, USA), and the International Space Science Institute (ISSI) in Bern (Switzerland) after completing of my PhD at the University of Bern in the Planetary Imaging Group.

My primary scientific interest is in small bodies of our Solar System. I study and analyse data acquired by interplanetary spacecraft. In particular, I’ve used data sets collected by the European Space Agency’s (ESA) spacecraft Rosetta to comet 67P/Churyumov-Gerasimenko, and NASA’s Lucy mission to the Trojan asteroids of Jupiter to understand the evolution of small bodies. Recently, I’ve also focused on understanding how planetesimals form in the early protoplanetary disk.

My Research

How did our Solar System form and evolve? What properties did the protoplanetary disk of the Solar System have? Did any of the first solid bodies in the Solar System survive to this day?
These questions lie at the heart of planetary science and form my research interests. Here you will find more information about my research and a list of peer reviewed papers.
