Maria Womack (@StarzanPlanets) is Research Professor of physics at the University of South Florida in Tampa. Her research involves multi-wavelength spectroscopy of comets and exoplanets. She is mainly interested in the chemical abundances and physical parameters that can be measured from volatiles with spectroscopic techniques. Lately, her cometary interests have focused on the activity of distant comets: those that are too far from the Sun for water ice to sublimate, but nonetheless have comae. Her work on exoplanetary science was mostly devoted to extracting signal from relatively faint ground-based spectra of hot Jupiters and super-Earths, which gave her a deep appreciation to the problems of Earth-atmosphere contamination.
Maria earned a B.S. in physics from Florida State University and a Ph.D. in physics from Arizona State University. She held a postdoctoral position in astronomy/planetary science at Northern Arizona University (Flagstaff) and her first faculty position was at Penn State Behrend (Erie). After three years, she left Erie to start a new faculty position at St. Cloud State University in Minnesota, where she worked for 18 years. She carried out research with over 60 undergraduate students and managed student-run observatories at both universities. From 2011-2015 she worked as a ‘rotating’ astronomy program director to the National Science Foundation. She used her cometary and exoplanetary expertise at NSF to manage the stellar and planetary astronomy individual investigator grant programs; and to help create and establish the joint NASA-NSF EXPLORE program for exoplanetary science. She started her USF faculty position in 2015 and occasionally helps out NSF as a part-time “expert.”
