Derek Fertig is a 4th year graduate student at George Mason University working on his PhD in physics. His research focuses on the gaseous and stellar components of interacting galaxies and how these interactions drive galaxy evolution. Using the Arecibo Legacy Fast ALFA (ALFALFA) survey, a large volume-limited HI 21cm line survey with the Arecibo telescope, and the Sloan Digital Sky Survey, he is investigating how gas content changes through galaxy interactions and how these changes relate to star formation enhancements seen in previous studies. He is also conducting a case study of the group environment, investigating how interactions within the galaxy group UGC 4670 drive changes in gas content and evolution for these galaxies which span the Hubble sequence. He conducts his research under the guidance of Dr. Jessica Rosenberg.
