Simon Foreman

Welcome! I am a postdoctoral fellow at CITA (the Canadian Institute for Theoretical Astrophysics), where I work on cosmology: the study of the evolution and contents of the universe as a whole. I'm interested in several topics related to current and upcoming observations on cosmological scales; these topics include line intensity mapping and its promise for cosmology, perturbation theory for large-scale structure, weak gravitational lensing, and efficient use of N-body simulations. I am also currently involved in the CCAT-prime collaboration and the Cosmic Visions 21cm working group.


A selection of research highlights can be found here.

Research History


  • I have contributed to codes for perturbation theory calculations, which can be found here, and a code (StringFast) for computing the effect of cosmic strings on CMB temperature and polarization power spectra, which can be found here.
  • Here is a collection of my favorite pedagogical resources for various topics.
  • If you've found this webpage by accident, you might be looking for one of these people instead.
