Dr. Marcus started her career as a Postdoctoral Fellow at the Woods Hole Oceanographic Institution, and after two years she was appointed to the scientific staff, where she remained for nine more years. She went to the Department of Oceanography at Florida State University in 1987, where she is currently a Professor. In August 2005 she became Dean of Graduate Studies at the Florida State University. Her graduate training was in ecology and evolutionary biology and to this day her research reflects this emphasis.
Her research focuses primarily on the phenomenon of dormancy in marine copepods, and she is now applying the acquired knowledge to the field of marine aquaculture. In recent years she has also turned her attention to evaluating the impact of reduced oxygen concentrations on the population dynamics of copepods. She also conducts work in the field, and in recent years her study sites have included the Gulf of Mexico, coastal waters off northern California, Narragansett Bay and the Gulf of Maine.
