After obtaining a BSc and MSc degree in physics at the University of Amsterdam, I received a PhD in astrophysics from Leiden University in 2015. In October 2015, I moved to the University of Chicago as a postdoc to join the Earths in Other Solar Systems research effort (part of NASA's Nexus for Exoplanetary System Science), a program that aims to understand the formation of habitable Earth-like planets. In 2017, I was awarded a Hubble Fellowship to continue my research at the University of Chicago.
I study the early stages of planet formation, where microscopic dust particles coalesce to form km-size planetesimals, the building blocks of planets. In particular, I am interested in how the dust's evolution influences the distribution of important volatiles (e.g., water, organics) in the protoplanetary nebula.
