Current research and/or projects

Dr. Gregory has been a research scientist at DFO since 2000. He has conducted research on fish nursery habitats for 30 years, including 15 years investigating marine fish nursery habitat in marine coastal waters of Newfoundland. Bob investigates habitat–population linkages, habitat-mediated juvenile fish survival and recruitment, fish movement and habitat associations, cumulative effects of anthropogenic environmental change and compensation mitigation of habitat change.

Bob is an Adjunct Professor of Biology at Memorial University of Newfoundland, where he has co-supervised and mentored 24 graduate students in the past decade, all of whom now work on aquatic ecology issues in various university, federal and provincial government research facilities, or in industry. He is the current and founding Director of the Centre of Expertise for Aquatic Habitat Research (CAHR).
