Personal profile
Biography
I am an astrophysicist at the UWA node of the International Centre for Radio Astronomy Research and the Director of the International Space Centre. I currently hold a Future Fellowship of the Australian Research Council.
I was born and raised in the German-speaking part of Switzerland. After graduating in theoretical physics at the Swiss Federal Institute of Technology (Lausanne, Switzerland) and the Carnegie Mellon University (Pittsburgh, US), I obtained my PhD in extragalactic astrophysics at the University of Oxford (UK) in 2009. Subsequently, I spent two years in the private industry before joining ICRAR/UWA as a faculty member in 2011.
My primary research lies in extragalactic astrophysics with a focus on the evolution of galaxies. I am also passionate about experimental research in microgravity and have served as a mission specialist on 354 parabolic flight manoeuvres aboard the Airbus Zero-G with the European Space Agency ESA.
