James Guillochon is currently a postdoc at the Institute for Theory and Computation in the Harvard astronomy department. He studies the tidal disruptions of stars by supermassive black holes and supernovae, runs hydrodynamical simulations to figure out their physics, and compares model predictions to observed data. He maintains Vox Charta and the Open Astronomy Catalogs (AKA Astrocats)
Steven Rieder (@rieder) is a postdoctoral researcher at RIKEN Advanced Institute for Computational Science in Kobe, Japan. He is a computational astronomer, investigating the interaction of objects on scales from planetary dust rings to the cosmic web. His simulation tool-of-choice for this is AMUSE : a Python interface to a range of community codes.
Born in the Netherlands, Steven did his MSc at Utrecht University and his PhD at Leiden University, on a combined astrophysics/computation science project. Parallel to his PhD, he was the editor of Dutch astronomy youth magazine “Universum” and a board member of the Dutch Youth Association for Astronomy “JWG”. He is an amateur observer, currently without access to a telescope. In no specific order, he is fond of photography, board games, cycling, exploring Japan, guitars and bunnies.
