The Lab

Stephen Gosnell, Principal Investigator

A native of South Carolina, Stephen completed his PhD at the University of California, Santa Barbara, and postdoctoral positions at the UCSB Marine Science Institute and the Florida State University Coastal and Marine Laboratory before joining Baruch College as an assistant professor in 2014.   His goal as an ecologist is to gather data on how communities are structured and what they provide so we can aid management and restoration efforts.  Much of his lab's work currently focuses on understanding coastal systems in and around New York.  The lab also asks similar question in other parts of the world through analysis of existing data sets and collaborations.

Stephen's research interests and approach also drive his work as a teacher.   He leads upper division courses on conservation biology and biostatistics, and enjoys introducing students to ecology through non-majors and first-year courses.  His courses typically use open educational resources in lieu of traditional textbooks in order to increase student access and bring current material into the classroom.  You can view material he has developed or aggregated for his courses under the teaching tab
