Dr. Jessica Werk is an astrophysicist at UC Santa Cruz and studies gas in and around galaxies. She is especially interested in the most extended, gaseous components of galaxies as they relate to the large flows of gas that are thought to dominate galaxy formation and evolution. Her research addresses two fundamental questions: how do galaxies get their gas? And, what do they do with it once they have it? She is an observer with expertise in optical and UV spectroscopy and photometry, who has had experience observing at nearly all wavelengths at many space and ground-based telescopes across the world.
