Jonathan Fisher

Jonathan Fisher Research Scientist
(709) 778-0652

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.

Maxime Geoffroy Research Scientist
(709) 778-0499

Dr. Maxime Geoffroy is a research scientist with expertise in bioacoustics, marine ecology and biological oceanography. His research aims at better understanding the ecology of North Atlantic and Arctic pelagic fish in relation to hydrography and climate change. In addition to ship-based surveys, he uses new technology, as unmanned vehicles and active acoustic moorings, to study marine ecosystems.

Prior to working at CFER, Maxime was a postdoctoral researcher at the Department of Arctic and Marine Biology of UiT the Arctic University of Norway. He holds a PhD in oceanography and an MSc in biology from Laval University, and a degree in mechanical engineering from the University of Ottawa.

Post Doc, PhD and MSc Students:

  • Dr. Gérald Darnis
  • Muriel Dunn
  • Jennifer Herbig (co-supervised by Jonathan Fisher)
  • Eugenie Jacobsen
  • Ashley Oates
  • Gabrielle Perugini
  • Einat Sandbank
  • Hannah Hynes
  • Julek Chawarski

Arnault Le Bris

Arnault Le Bris Research Scientist
(7090 778-0482

Dr. Arnault Le Bris is a research scientist with interests in understanding and quantifying processes that drive the dynamics of marine fish and shellfish populations. His past and present work has focused on evaluating how climate variability and change affects the productivity of living marine resources, and how fish migration affects the sustainable management of fisheries resources.

Originally from the Brittany region in France, Arnault first came to Newfoundland in 2009 to pursue his doctoral studies in fisheries ecology at Memorial University of Newfoundland. Before joining CFER, he was a postdoctoral fellow at the Gulf of Maine Research Institute in Portland Maine, USA.

Sherrylynn Rowe

Sherrylynn Rowe Research Scientist
(709) 778-0318

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.

Tyler Eddy Research Scientist

Tyler Eddy Research Scientist

Dr. Tyler Eddy is the team lead at The Life Aquatic and is a Research Scientist at the Centre for Fisheries Ecosystems Research (CFER) Marine Institute, Memorial University of Newfoundland. Tyler lectures in the Fisheries Science Graduate Program and teaches ‘Data Collection, Management, & Display’.

Matthew Robertson

Matthew Robertson Research Scientist

Dr. Matthew Robertson is a research scientist with CFER.  Matthew’s research focuses on answering ecological and population dynamics questions in fisheries, and how those questions can be addressed to improve ecosystem-based fisheries management advice. He also teaches the ‘Statistics and Study Design for Fisheries Science’ in the Fisheries Science Graduate Program.

Matthew is a 2023 graduate of Memorial University where he received his PhD in Fisheries Science. His PhD research focused on assessing the differential recovery trajectories of flatfish on the Newfoundland Grand Banks. Prior to attending Memorial University, Matthew graduated from Louisiana State University with an MSc in Oceanography and from Dalhousie University, where he received a BSc with Honours in Marine Biology.
