President's Outstanding Faculty Award for Scholarship & Creative Activity
Prof. Dominguez’s current research is focused on recreating physical-chemical conditions in the lab that mimic those found in molecular clouds, the birthplaces of stars, and protoplanetary disks. Specifically, Dominguez’s lab is studying how isotopes of oxygen and hydrogen change as a result of interacting with interstellar dust grains and cosmic-ray induced radiation as well as how the formation of water itself selects for these isotopes. Lab experiments and theoretical work are providing new insights into the early history of the solar system, the origins of water, and the relationship between the isotopic composition of the Sun, comets, and the planets. Other research interests include applications of nano-infrared spectroscopy in the geophysical, geochemical, and astronomical sciences.
