Interests
My research focuses on the use of radio, millimeter, and submillimeter
observations of interstellar matter to probe how galaxy evolution unfolds in
the nearby and distant universe. Particular interests include the properties
of dusty star-forming galaxies — e.g., low-z ultraluminous
infrared galaxies (ULIRGs), and high-z submillimeter galaxies (SMGs)
like those seen by the Atacama Cosmology Telescope (ACT) — and the
growth of stellar disks and central black holes in nearby, normal galaxies.
I am also interested in the cosmic evolution of neutral atomic hydrogen,
which I will be studying out to z = 1.4 with South Africa's new MeerKAT interferometer
in the context of the 3424-hour LADUMA survey. LADUMA's status as one of the three
top-ranked MeerKAT Large Survey Projects was reconfirmed in June 2017 by an
international review panel.
