Simon’s current activities primarily focus on 21cm intensity mapping, a (relatively) new way to probe the cosmic distribution of matter by measuring radiation from distant clouds of neutral hydrogen. He is a member of the CHIME collaboration, which is currently analyzing data from a custom-built radio telescope designed for this technique, and the PUMA proposing team, which is developing a concept for a next-generation telescope that would use 21cm intensity mapping to obtain transformative cosmological constraints. At MIT, he will also begin work within the CHORD collaboration, which has received funding from the Canadian government to construct and operate a successor telescope to CHIME.
Beyond this, Simon has broad interests in cosmology, and has worked on perturbation theory for large-scale structure, baryonic effects on large-scale clustering, non-21cm line intensity mapping, and several other topics. Simon received a BSc in physics and mathematics from the University of British Columbia and a PhD in physics from Stanford University, and previously held postdoctoral positions at the Canadian Institute for Theoretical Astrophysics and the Perimeter Institute for Theoretical Physics.
