Dr. Steve Auscavitch (he/him/his) is a visiting scholar and postdoctoral researcher in the Rotjan Lab. His research broadly seeks to understand ecological patterns and processes in deep-water coral ecosystems, particularly on seamounts. His current project in the lab seeks to identify and describe protected deep-water coral biodiversity, as well as patterns in phylogenetic community structure, in the Phoenix Islands Protected Area and surrounding waters. His work leverages data collected from remotely operated vehicles with existing collection resources present in museum archives. Steve is also an active member of the Corp of Exploration on the E/V Nautilus where he has contributed as science lead and science data manager on several cruises since 2014. He received his BS in Marine Science from the University of Connecticut at Avery Point, his MS in Marine Biology at the University of Maine, and PhD in Biology from Temple University. You can follow him on Twitter @SteveAuscavitch and via his personal website.
