Professor, National Astronomical Observatories, Chinese Academy of Sciences
Prof Roberto Soria is an astrophysicist at the University of the Chinese Academy of Sciences, Beijing. He is also Affiliate Staff at The University of Sydney. His research focuses on how matter falls into black holes, on the properties of collapsed objects (black holes and neutron stars) and on their relation with star-forming galaxies. Before moving to Beijing, he worked at University College London, Tsinghua University, the Harvard-Smithsonian Center for Astrophysics, and ICRAR-Curtin University. He received his PhD from the Australian National University (Mount Stromlo Observatory). He is an active member of the Astronomical Society of Australia, the Royal Astronomical Society, and the MacArthur Astronomical Society. He is by nature deeply skeptical of trumped-up scientific consensus, of Big Government actions for-our-own-good, and of the results of his own research.
