Research interests

The underlying objective of my research is to improve the characterization of human exposures and risks from environmental contamination. I'm particularly interested in the development of tools and approaches that: (i) quantify the health risks from dietary contaminants, (ii) develop optimal intervention strategies where necessary, and (iii) explore the extent to which nutrients offset contaminant risks. To these ends, I have undertaken a two-pronged research program that: a) examines population level contaminant exposure through biomonitoring; and b) investigates the ways and means by which selenium and omega-3 fatty acids counter the health risks posed by methylmercury.

Graduate supervision and student opportunities

I am currently accepting applications from graduate students with related research interests:

  • Toxicology
  • Exposure science
  • Environmental health
  • Risk assessment

MSc Public Health and Health Systems candidate, Danielle Brandow works with Professor Laird researching links between contaminant exposure, nutritional status, and food use in First Nation and Metis communities in the Northwest Territories. Watch Danielle's research experience from her perspective.
