Doug Crump

Molecular Toxicologist - Avian Species

CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate to ensure wildlife is conserved and protected

  • Toxicogenomics – Use of in vitro (cell culture) and in ovo (egg injection) approaches to determine the effects of priority environmental contaminants (e.g., brominated flame retardants) on gene expression in avian species
  • Identify novel mechanisms of action of priority chemicals (e.g., thyroid hormone disruption)
  • Field assessments of the health of colonial bird populations at contaminated sites on the Great Lakes using Herring Gulls as a model species
  • Conservation genetics – Use DNA obtained from avian material (i.e., eggshells, feathers, blood) to determine sex, relatedness, parentage and embryonic viability

PROFESSIONAL ACTIVITIES / INTERESTS

Co-supervise 4th-year Honours students from University of Ottawa and Carleton University
