Amy R. Knowlton, M.M.A.

Research Scientist

B.A. Boston University, 1982, Geography
M.M.A. University of Rhode Island, 1997, Master of Marine Affairs

Research Interests: Amy’s main interest is meshing science with policy to help develop effective protection measures for right whales. She has worked to this end on both the ship strike issue and the fishing gear entanglement problem by assessing the level of impact of these activities on right whales and helping to develop policy changes to mitigate these impacts. She is also interested in photo-identification and population monitoring efforts. In addition, Amy has also worked to develop education modules for maritime academies about right whales and ship strikes.

Current Projects: Assessment of entanglement and ship strike interactions with the Right Whale Research project, supervision of photo-identification efforts, education and outreach to mariners and the general public

Scott D Kraus, Ph.D.

Vice President for Research

B.A. College of the Atlantic, 1977, Human Ecology
M.S. Univ. of Massachusetts, 1991, Biology
Ph.D. Univ. of New Hampshire, 2002, Zoology

Research Interests: Dr. Kraus is interested in the biology and conservation problems facing North Atlantic right whales, and also conducts research on methods to reduce bycatch of marine mammals in fishing gear. His recent work on biological hotspots has been focused on trying to understand the connections between the physical oceanography, plankton, fish, and the aggregations of whales and dolphins that such locations attract. He has published over 70 scientific papers on cetacean biology and conservation, and is adjunct faculty at Univ. of Mass. at Boston and the University of Southern Maine. Kraus’ recent research is increasingly focused on conservation issues faced by endangered marine species and habitats, and the difficulties of identifying what animals need to survive in an increasingly urban ocean.

Current Projects: Right Whale population biology and conservation, Bycatch Reduction Consortium, marine biological hotspots and oceanographic factors that create them

B.A. University of Rochester, 1996, Psychology
Ph.D. Northeastern University, 2006, Biology

Research Interests: The physiological ecology and conservation physiology of elasmobranch fishes (sharks, stingrays and skates) and other fishes. More specifically: 1) the physiological consequences of exposure to anthropogenic stressors in fishes; 2) the mortality of discarded bycatch in fishing operations; 3) strategies to reduce discard mortality.

Current Projects: Elucidating post-release mortality and ‘best capture and handling’ methods in sublegal Atlantic cod discarded in Gulf of Maine recreational hook fisheries (funded by NOAA/NMFS Bycatch Reduction Engineering Program); Evaluating the condition and discard mortality of skates following capture and handling in the sea scallop dredge fishery (funded by NOAA/NMFS Scallop Research Set Aside Program); Conservation physiology of sharks and rays in the Bahamas (funded by private research gift).

Daniel E. Pendleton, Ph.D.
Research Scientist
B.S. Mathematics, Minnesota State University, 1999
M.S. Soil Science, Cornell University, 2003
Ph.D. Natural Resources, Cornell University, 2010

Research Interests: Using modern quantitative techniques to address contemporary issues in marine resource management, particularly those pertaining to endangered species. Incorporating satellite- and model-derived environmental data into statistical models to answer questions about the spatial and temporal distribution, and habitat preferences, of organisms such as the Western Arctic bowhead whale (Balaena mysticetus) and North Atlantic right whale (Eubalaena glacialis).

Current Projects: Forecasting Changes in Habitat Use by Bowhead Whales in Response to Arctic Climate Change: Integration of Physical-Biological Models with Satellite, Biological Survey and Oceanographic Data. Funded by the NASA Biodiversity and Ecological Forecasting program.

Rosalind M. Rolland D.V.M. (C.V.)

Senior Scientist, Marine Conservation Medicine

B.S. University of Wisconsin-Madison, 1978, Natural Sciences
D.V.M. Tufts University School of Veterinary Medicine, 1984, Veterinary Medicine

Research Interests: Dr. Rolland’s research is focused upon the connections between the health of wildlife populations and the health of the ecosystems where they live. She previously worked on endocrine-disrupting chemicals as a Conservation Scientist at the World Wildlife Fund-U.S., then served as Assistant Professor and Science Director of the Center for Conservation Medicine at Tufts Veterinary School. She has over 30 scientific publications, and has held appointments at Harvard Medical School and the University of North Carolina-Wilmington. Dr. Rolland has pioneered the development of non-invasive methods to study health and reproduction in North Atlantic right whales, in order to better understand the risks posed to these highly endangered whales by human impacts on their marine habitat.

Current Projects: Reproduction and stress physiology in right whales using fecal hormones, visual health assessment of whales, exposure of right whales to marine biotoxins, pathogenic protozoa in right whales, use of scent detection dogs for sampling whales

Randi D. Rotjan, Ph.D.

Associate Scientist

B.S. Cornell University, 1999, Neurobiology and Behavior
Ph.D. Tufts University, 2007, Biology

Research Interests: Dr. Rotjan's research addresses the interface between ecology, symbiosis, and behavior to ultimately determine how organisms interact with their environments. Although she works on a wide variety of model organisms, Randi most often works on ecosystem engineers, which are organisms that have a disproportionate influence on their habitat (such as reef-building corals). Randi uses an integrative approach, combining exploratory observations with manipulative experiments to discover the patterns and uncover the mechanisms guiding ecosystem engineer performance. In addition, Dr. Rotjan also studies hermit crab shell choice behavior, the conservation ecology of tropical reef communities, trophic dynamics and corallivory, and the evolution and ecology of symbiosis in marine invertebrates. She provides updates on her research in the Phoenix Islands on the Phoenix Islands Expedition blog.

Current Projects: Biological effects of offshore LNG port areas (Funded by Excelerate Energy, L.L.C. & Suez Energy North America, Inc.), the ecology and symbiosis of tropical and temperate corals, bacterial symbioses in deep-sea hydrothermal vents, and hermit crab shell choice behavior
