2020/07/29: I co-authored a paper on the activity of asteroid 6478 Gault, led by Zhong-Yi Lin.
2020/06/15: I have been nominated as Coordinator of the scientific theme "Near Environment" for the Comet Interceptor mission. This is ESA's first F-class mission; our goal is is to characterise, a dynamically-new comet or interstellar object with a fleet of 3 spacecrafts.

I am a planetary scientist working with space missions and ground based observations of Solar System objects. I am currently based at the DLR Institute of Planetary Research in Berlin, Germany. My detailed Curriculum Vitae is available as a pdf file.

My research focuses on the evolution of asteroid and comets, through studies of their surface properties and activity. These objects are remnants from the early age of our Solar System, and the bricks from which planets, water, and life may have been formed.
Observations only give us access to their current surface, which has been heavily processed for billions of years. Understanding this evolution and the physical processes responsible is the key to decipher the formation and evolution of the Solar System.

Since 2019 I am leading an ISSI international team looking at the outcome of collisions in the Early Outer Solar System.

I am a Co-Investigator or associate in many space missions: Rosetta, Dawn, CAESAR, AIDA (DART+Hera), Hayabusa 2, MMX, with direct access to a wealth of in situ observations of asteroids and comets.

My analysis of these data sets has led to new views on cometary activity, surface evolution, as well as crater morphology and physical properties of asteroid regolith.
I have developed a numerical model describing the release of cometary dust and gas jets. This code and its results have been actively used for the planning of the mission Stardust/Next and the planning and data analysis of the Rosetta mission.

My work on comets and asteroids is now also being applied to the study of Main Belt Comets/Active asteroids and KBOs.
