Simon Foreman is an Assistant Professor in the Department of Physics. His research centers on cosmology - the study of the evolution, contents, and fundamental laws of the universe as a whole - and uses a combination of theory, simulations, and data analysis, with the common theme of developing methods for learning more about the universe.
A major focus of Foreman's research is 21cm intensity mapping, a way to probe the cosmic distribution of matter by measuring radiation from distant clouds of neutral hydrogen, and use these measurements to place interesting constraints on cosmology and fundamental physics. He is a member of the CHIME collaboration, which is currently analyzing data from a custom-built radio telescope designed for this technique; the CHORD collaboration, which is building a successor telescope to CHIME; and the PUMA proposing team, which is developing a concept for a next-generation telescope for 21cm intensity mapping. In parallel, he pursues more general research into cosmic large-scale structure, the cosmic microwave background, and related topics.
