I joined the University of Exeter in 2013. Before that, I held appointments as NASA Sagan Fellow at the University of Michigan and as SMA fellow at the Harvard-Smithsonian Center for Astrophysics. I received my Ph.D. from the University of Bonn and my M.Sc. from the University of Massachusetts.

My research focuses on high-angular resolution studies related to star and planet formation. Using interferometers such as VLTI, CHARA, and ALMA I study the inner regions of protoplanetary discs and the physics that govern the inner few astronomical units. Using these observations, I investigate how planets and multiple stellar systems are forming and the dynamical processes that shape the architecture of stellar multiple systems and planetary systems.

Further details of my research projects and on my research group can be found on my personal website.
