Directors and Scientists

Thomas Brown

Thomas Brown
Administrative Director 778-0336

Thomas Brown hails from St. Anthony and holds a bachelor of science (Honours) in biology and a master's degree in fisheries resource management from Memorial University. After graduation, Tom obtained contractual employment as an aquaculture project officer with Fisheries and Oceans Canada, and went on to become Newfoundland operations manager for Tavel Limited, a dockside grading company.

In October 2003, Tom accepted a position as assistant director of the Centre for Aquaculture and Seafood Development. In 2010 Tom played an integral role in the development and creation of CFER and has since become administrative director of the Centre.

Noel Cadigan

Noel Cadigan Quantitative Fisheries Scientist

Dr. Noel Cadigan is a quantitative fisheries scientist specializing in statistical methods for fish stock assessment and sustainable fisheries. He has extensive experience in the assessment of Newfoundland fish stocks, and experience with other Canadian, American and European stocks.

He received a doctor of philosophy in statistics in 1999 at the University of Waterloo, a master of applied statistics in 1993 and a bachelor of science (Honours) in 1990 from Memorial University.

He worked with Fisheries and Oceans Canada at the Northwest Atlantic Fisheries Center in Newfoundland from 1990-2011 (with a 2-year break to pursue his studies) and focused on the assessment of Atlantic cod and other groundfish stocks.

Dr. Cadigan is a cross-appointed member in the Department of Mathematics and Statistics at Memorial University and has supervised graduate students in statistics whose research involved applications to stock assessment problems.

Marie Clément

Marie Clément Aquatic Research Scientist

Dr. Marie Clément holds a master of science in biology from the University of New Brunswick and a doctor of philosophy in zoology from the University of Guelph. Prior to joining CFER, Marie worked for the Department of Fisheries and Oceans for 11 years (2001 – 2012).

She began her career as an Atlantic salmon stock assessment biologist.

Since 2004, she has studied the effects of anthropogenic activities on riverine habitat and fish populations and the efficiency of mitigation measures (e.g., peatland exploitation, timber harvesting, dam removal and fishways passage efficiency). Using fin tissue stable isotope and otolith microchemistry analyses, she also investigated migration patterns of American eel between saline summer feeding grounds to freshwater overwintering.

Her current research interests focus on quantifying the effects of anthropogenic activities on freshwater and estuarine ecosystems, including the effects of hydro-electric dams, mining and climate change. More specifically, she is interested in bioaccumulation of mercury in food webs, instream flow requirements, sediment transport and alteration of life-history traits in fishes.

Jonathan Fisher

Jonathan Fisher Research Scientist

Dr. Jonathan Fisher is a research scientist with interests in the structure, functioning and dynamics of marine ecosystems. He has research experience in population, community and ecosystem ecology of exploited and unexploited systems in the Northwest Atlantic.

Most recently, Jonathan was a postdoctoral fellow in the Department of Biology at Queen's University and the Bedford Institute of Oceanography. He received his doctor of philosophy from the University of Pennsylvania, a master of science from Dalhousie University and a bachelor of science (Honours) from Queen's University.

Dominique Robert

Dominique Robert Research Scientist

Dr. Dominique Robert is a research scientist with interests in understanding bottom-up processes driving the recruitment of marine fish populations. A large portion of his past and current work has focused on the relationships linking zooplankton prey production to larval fish feeding success, growth and survival.

Prior to joining the Centre, Dominique was a research fellow with the ArcticNet NCE, investigating the impact of climate change on Arctic cod populations in the Canadian Arctic based on otolith microstructure analysis and acoustic detection. Hailing from Quebec City, he received his doctor of philosophy from Université Laval, and was a postdoctoral fellow at Kyoto University.

Sherrylynn Rowe

Sherrylynn Rowe Research Scientist

Dr. Sherrylynn Rowe is a research scientist with CFER. Prior to joining the Centre, Sherrylynn was a research scientist with Fisheries and Oceans Canada at the Bedford Institute of Oceanography.

She received a doctor of philosophy from Dalhousie University as well as a master of science and a bachelor of science (Honours) from Memorial University. Sherrylynn's recent scientific efforts have focused on stock assessment and related research involving ecology and life history of groundfish and marine invertebrates.

Her earlier studies examined linkages between spawning behaviour and population dynamics of Atlantic cod and the role of marine protected areas in enhancing lobster populations and fisheries.

Christoph Konrad Postdoctoral Fellow

Dr. Christoph Konrad is a postdoctoral fellow at CFER. Prior to his appointment, he worked on the EcoFishMan Project at the University of Aberdeen linking the ecological impact of fisheries and the economic revenue of fisheries in the North Sea.

Christoph was awarded a doctor of philosophy in theoretical ecology as well as a bachelors of science (honours) in zoology at the University of Aberdeen. In between, he received a masters of research at the University of St. Andrews. Christoph's doctoral thesis looked at the development and application of random-walk models. At CFER, Christoph will be analysing cod-tag data from the NAFO divisions 3P4RS and 2J3KL to enhance the understanding of cod stock dynamics, such as growth rates, migration patterns and, especially, the selectivity of effective gear.

Hannah Murphy Postdoctoral Fellow

Dr. Hannah Murphy is a postdoctoral fellow with CFER. Hannah’s research focuses on fish larval trophodynamics (food-web dynamics). During her doctoral research at the University of Melbourne, Australia, Hannah investigated how zooplankton availability (bottom-up processes) affected larval survival and recruitment of snapper, a temperate marine fish. Before moving to Newfoundland, Hannah lived in Vancouver, British Columbia where she completed a bachelor of science at the University of British Columbia, and in Melbourne, Australia where she completed a bachelor of science (Honours) and a doctor of philosophy at the University of Melbourne. Hannah’s research at CFER will focus on how larval growth affects capelin survival and recruitment, as well as an acoustic project on halibut.

Tharshanna Nadarajah Postdoctoral Fellow

Tharshanna Nadarajah is a Research Assistant working with Dr. Noel Cadigan. A PhD candidate in statistics at Memorial University, he holds a master of science in statistics from Memorial, a master of science in applied statistics from University of Peradeniya, Sri Lanka and a bachelor's degree in statistics and computer science from Eastern University, Sri Lanka. Tharshanna’s current research at CFER involves modelling the growth of fish.
