Employment

Oct 2020 – present Dunlap Institute for Astronomy & Astrophysics, University of Toronto, Canada Dunlap

Oct 2017 – Oct 2020 Oskar Klein Centre for Cosmoparticle Physics, Stockholm University, Sweden Oskar Klein Centre Postdoctoral Fellow

I test cosmological models using large and complex datasets -- and develop and apply novel statistical/ML methods to improve that inference. I study the cosmic microwave background and large-scale structure -- specifically the Lyman-alpha forest, the absorption from neutral gas in the early Universe observed in the spectra of quasars. These complementary observations allow us to test many extensions to the standard cosmological model -- e.g., the properties of neutrinos, models of cosmic or the phenomenology of dark matter (e.g., ultra-light axions).
