Eric Carlson
Eric Carlson’s research covers a variety of topics including both particle phenomenology and astrophysics. These topics include pseudoscalar couplings, the existence of a naturally small cosmological constant, and neutrino physics. Carlson believes astroparticle physics to be one of the most promising areas in particle phenomenology in the next decade or two

Caitlin Witt
Caitlin Witt’s research interests are in the areas of observational and computational astrophysics. Her research centers on supermassive black hole binaries using multimessenger astrophysics, where she combines electromagnetic and gravitational-wave data. Witt and her collaborators use pulsars to search for decades-long gravitational wave signals, time-domain optical surveys to search for binaries, and supercomputers to analyze the data to provide a complete picture of the aftermath of galaxy mergers.
