Prof Pusack’s research focuses on why and how species exists in their particular habitats. His work includes studies of community ecology, species interactions, dispersal, and adaptation. For his Ph.D. at Oregon State University, he used genetic and field ecology techniques to study larval dispersal and the Lionfish invasion. As a Post-Doctoral Scholar at the University of South Florida, he studied how fluctuation in abiotic conditions affected species interactions on and persistence of oyster reefs.
