    Dr. Bradley Stevens is a tenured Professor of Environmental Science in the Department of Natural Sciences at the University of Maryland Eastern Shore, and Distinguished Research Scientist with the NOAA Living Marine Resources Cooperative Science Center. He is also a Graduate Faculty member of the University of Maryland Marine, Estuarine, and Environmental Sciences (MEES) Graduate Program.  He received his PhD from the University of Washington under Dr. David Armstrong, Director of the School of Aquatic and Fisheries Sciences (ret.).  He previously worked for the National Marine Fisheries Service of NOAA for 22 years in Kodiak, Alaska, where he was Task Leader for Bering Sea Crab Stock Assessment, managed the Seawater Laboratory at the Kodiak Fisheries Research Center, and was Acting Director of the NMFS Kodiak Laboratory in 2006.  In 2006 he left Alaska (and NOAA) to join the University of Massachusetts as an Associate Professor, and in 2009 moved to the University of Maryland Eastern Shore as full Professor.  He has authored or co-authored over 65 peer-reviewed publications and conference proceedings, and is the Editor and principal author of “King Crabs of the World”, CRC Press, 2014.   Since 2007, he has advised 14 graduate students in Massachusetts and Maryland. 

    Dr. Stevens’ research program focuses on ecology and reproductive biology of invertebrates (primarily crabs), and impacts of fishing on fish and invertebrate populations and their habitats. Since 2009, he has brought in >$1,000,000 in grants as P.I., and has co-authored grants totaling >$30,000,000.  His teaching specialties include statistical computing with R, and sampling theory for population assessments.  In 2015, he initiated the AAUS Diving program at UMES, and currently serves on the University System of Maryland Diving Control Board.
