Professor Mike Boylan-Kolchin is a theoretical astrophysicist who works on galaxy formation theory and its interface with cosmology. Recently, his research has focused on near-field cosmology, using detailed studies of nearby galaxies to address a wide variety of questions related to dark matter and galaxy formation physics across cosmic time. His work combines numerical simulations, analytic models, and observations.

Cosmology and galaxy formation, including:

  • the formation, evolution, and structure of galaxies and dark matter halos
  • the nature of dark matter
  • near-field cosmology
  • cosmic reionization
  • numerical simulations
