Profile

Since 2005, my faculty position in the Department of Integrative Biology has been co-sponsored by the University of Guelph and the Chippewas of Nawash Unceded First Nation - an Ojibway community on the Saugeen (Bruce) Peninsula of Lake Huron, Ontario. After a decade of working with the Saugeen Ojibway Nation (SON=Nawash and Saugeen First Nation, collectively) on research and management issues associated with their Constitutionally-protected Aboriginal fisheries, my efforts shifted significantly to this academic environment. Under terms of the Nawash-UG Memorandum of Agreement, my work is organized in three major areas that provide overlapping benefits to both sponsoring partners: Research (Nawash/UG), Service (Nawash/UG), and Teaching (UG).

Education

B.Sc. - University Guelph (1985)
M.Sc. - Queen's University (1987)
Ph.D. - University of Guelph (1993)

Research

As defined in the Nawash-UG MOA, my research program is divided into three major themes that vary over time in response to specific needs of Nawash/SON and the opportunity for innovative scholarly collaborations.

1. Great Lakes Fish Ecology

My initial training as a fish ecologist has continued over the past decades in several forms, including: developmental biology, animal behaviour, fish habitat, effect of exotic species, species-at-risk, fish population and community dynamics, and the response of ecosystems to natural and human disturbance. Currently, I am engaged in development and implementation of the following research projects associated with priority issues in the SON traditional territory:

  • Effects of the Bruce Nuclear Generating Station on lake whitefish population(s) in Lake Huron
  • Larval fish nursery habitat evaluation in nearshore waters of the Great Lakes
  • Ecological factors associated with native and non-native salmonid population dynamics

2. Science in Natural Resource Management

Much of my service with Nawash/SON has been focused on their Nation-to-Nation resource management negotiations with Canada (Fisheries & Oceans Canada, Environment Canada, Canadian Nuclear Safety Commission), Ontario (Ministry of Natural Resources, Ministry of Environment), as well as Industry and Environmental NGOs. Consistently, one of the major issues in these negotiations is the quality of science in management decision-making - especially as it relates to role of hypotheses and empirical evidence to evaluate uncertainty in (a) states of nature, and (b) consequences of proposed management actions (e.g., fisheries harvests, habitat alteration, cooling water intake systems). Currently, I am engaged in development and implementation of the following research projects associated with priority issues in the SON traditional territory:

  • Determination of safe harvest limits for Lake Huron fisheries
  • Re-incorporation of 'fish habitat' protection in the Canadian Fisheries Act
  • Development of Canadian regulatory framework for nuclear power plant entrainment/impingement

3. Indigenous-Western Science Knowledge Systems

When Nawash requested me to critically examine the theoretical and practical basis for engagement between their traditional knowledge holders and 'Western' scientists/managers, I had no idea about the depth and breadth of these issues. I was very fortunate to receive strategic support from the Social Sciences and Humanities Research Council of Canada that enabled me to establish insightful collaborations with Ojibway, Haudenosaunee and Maori scholars who helped me begin to recognize the fundamental concept of knowledge systems in both Indigenous and Science cultural dynamics. Currently, I am engaged in a research program with Dr. Jeji Varghese (UG Sociology) with the following research projects:

  • Knowledge Systems as a practical framework for cross-cultural, multidisciplinary engagement
  • Cultural history and relevance of 'Western' science for modern Indigenous communities
  • Survey of Western scholars' understanding of science in theory and practice
  • Rigorous examination of published scientific knowledge: polar bear population ecology as a case study
