observational faculty

Using a wide range of world-class observational facilities, including the ground-based Keck Observatory, Rubin Observatory, Las Cumbres Observatory, South Pole Telescope, as well as the spaced-based Hubble and James Webb Space Telescopes, our research spans a diverse range of topics, including cosmology, large-scale structure, dark matter, dark energy, clusters of galaxies, galaxy formation, supernovae, and stellar evolution.

Christopher Fassnacht
strong gravitational lensing, dark-matter substructure, the expansion of the Universe and the Hubble Constant

Tucker Jones
galaxy formation

Lori Lubin
clusters of galaxies

Stefano Valenti
time domain astronomy, supernovae, stellar evolution

David Wittman

theoretical faculty

Our theoretical research also spans a wide range of topics, including cosmology, dark matter, dark energy, large-scale structure, the cosmic microwave background, cosmological structure formation, galaxy formation, supermassive black holes, and stars. Much of this work is highly computational, using the nation's most powerful supercomputers.
