Directors and Scientists

Thomas Brown

Thomas Brown Administrative Director

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.

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.

Jin Gao Research Scientist

Jin Gao Research Scientist

Dr. Jin Gao is a research scientist at CFER, and a junior Ocean Choice International (OCI) Industrial Research Chair in Fish Stock Assessment and Sustainable Harvest Advice for Northwest Atlantic Fisheries. She is a broadly trained quantitative ecologist who is particularly interested in fishery science.

She develops and applies modern statistical methods to improve stock assessment. Her current work focuses on methods to improve abundance estimates by incorporating developments in spatio-temporal modeling and improve forecasting using equation-free nonlinear time series analysis.

Jin did her second postdoctoral research at a joint position of the School of Aquatic and Fishery Sciences in the University of Washington and the Northwest Fisheries Science Center of NOAA. She did her first postdoctoral research at the Institute of Oceanography in the National Taiwan University.

She obtained a PhD degree in Ecology and Evolution at the State University of New York at Stony Brook and a Bachelor’s degree in Ecology at Shandong University, China.

Maxime Geoffroy Research Scientist

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.

Arnault Le Bris

Arnault Le Bris Research Scientist

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

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.

Dr. Fan Zhang Research Scientist

Dr. Fan Zhang Research Scientist

Dr. Fan Zhang is a research scientist at CFER, and a junior Ocean Choice International (OCI) Industrial Research Chair in Fish Stock Assessment and Sustainable Harvest Advice for Northwest Atlantic Fisheries. His research mainly focuses on the spatio-temporal recruitment dynamics of important fish species on the Grand Banks, which will contribute to improve stock assessment models for important Northwest Atlantic Fisheries. He is interested in a holistic approach to fisheries problems by combining ecological and social aspects of fisheries systems. He aims to study fish recruitment dynamics in the context of complex adaptive social-ecological system, and most of his research involves developing and/or improving statistical and mathematical models as well as computer simulations.

Fan did his postdoctoral research with the Department of Integrative Biology, University of Guelph. He obtained a PhD degree in integrative biology from University of Guelph, a Master’s degree in fisheries resources and a Bachelor’s degree in marine biological resources and the environment from the Ocean University of China.

Dr. Nan Zheng OFI Post-Doctoral Fellow

Dr. Nan Zheng joined CFER as an OFI Post-Doctoral Fellow in September 2017. His work is primarily focusing on developing spatial stock assessment models for Grand Banks flatfish.

Nan Zheng earned his MSc. in 2013 and PhD in 2017 from the Department of Mathematics and Statistics at MUN. His MSc. work was in financial time series, and his PhD work was in semi-parametric fixed and mixed models for longitudinal discrete data. He was awarded the Dean's Award for 2013-17 as well as the titles of Fellow of the School of Graduate Studies 2013-14 and 2017-18 for his MSc. and PhD studies respectively.

Nan Zheng received his BSc. degree from Zhejiang University in China. His previous work was in general relativity, solid state physics, and optics.

Tyler Eddy Research Scientist

Tyler Eddy Research Scientist

Dr. Tyler Eddy is a research scientist interested in past, present, and future human interactions with, and ecology of, marine ecosystems. He has experience in marine ecology, fisheries, climate change, ecosystem modelling, marine conservation, and historical ecology.

Dr. Eddy was a postdoctoral fellow at Dalhousie University, a Nereus research associate at the University of British Columbia, and a Nereus research fellow at the University of South Carolina, US. Dr. Eddy received his doctor of philosophy in marine biology from the Victoria University of Wellington, New Zealand and an Honours bachelor of science in marine biology from Dalhousie University.
