August (Gus) Evrard is Arthur F. Thurnau Professor in the departments of Physics and Astronomy, and the Michigan Center for Theoretical Physics. He serves as Associate Director for Community Engagement with ARC. Professor Evrard is a computational cosmologist who models the formation and evolution of large-scale cosmic structure. He currently co-leads the Simulation Working Group for the US-led Dark Energy Survey and is a member of the XMM-XXL project and Virgo Consortium based in Europe. His research uses N-body and hydrodynamic methods to study the formation of galaxies and clusters of galaxies. The simulations also produce synthetic expectations for astronomical sky surveys, providing truth tables that are essential for verifying data handling and statistical processing methods applied to survey data to study the nature of dark matter and dark energy. Professor Evrard was named a Fellow of the American Physical Society in 2011 and an ORCID Ambassador in 2013. He is active in instructional technology at Michigan, founding the Academic Reporting Tool service in use since 2006 and Problem Roulette, a cloud-based study service that offers random, topical access to old exam questions for students in introductory physics classes.
