Biography

Research - Major activities

Many environmental chemicals that contaminate human foodstuffs and natural chemicals occurring in food that possess hormonal activity, are considered as possible endocrine disrupters with reproductive implications for human development and fertility. Investigations use in vivo and in vitro approaches to examine the mechanisms of toxicity of these chemicals.

Current funding

2003 - 2006 NSERC (PI D. Cyr) A novel pharmacokinetic-gene expression model model for toxicological risk assessment of endocrine disrupting chemicals. $183,000

2004 - 2004 ISC (with D. Forsyth) Speciation of organotins in whole fetuses, fetal tissues and milk following daily oral administration of tributyltin chloride to pregnant and lactating rat dams. $14, 500
