Toxicology Group

The Toxicology Group is an interdisciplinary body under the umbrella of the College of Graduate Studies and Research. It consists of faculty members from a number of University departments, as well as scientists from various research centres on campus. The Toxicology Group is coordinated and managed by the Toxicology Centre. Scientists with academic or research interests in toxicology, who work at the University of Saskatchewan or any of the federal or provincial agencies or private sector laboratories on or near campus, are eligible to become members of the Group. Two types of membership may be granted: members are those currently involved in research or teaching specifically related to toxicology; associate members are those who have a principal interest in toxicology, but are not presently engaged in active research or teaching in the field of toxicology.

The mandate of the Group is to: maintain and support academic programs in toxicology at the University of Saskatchewan; promote and facilitate research in toxicology; promote public awareness and engage in community consultation on important issues in the area of toxicology; and to work cooperatively and collaboratively with all academic units participating in toxicology and address difficulties when they arise in matters involving shared resources. The Group is headed by a Chair, who is the Director of the Toxicology Centre, or his or her designate. The Chair is assisted by an Executive Committee, elected every three years by the membership. The Executive Committee consists of an Academic Coordinator, two members-at-large elected by the membership, one member-at-large elected by the Toxicology Centre, and the Dean, College of Graduate Studies and Research (ex officio). Members of the Toxicology Group are eligible to serve as supervisors for students enrolled in M.Sc. and Ph.D. programs in Toxicology. They are actively engaged in research across a broad spectrum of toxicology sub-disciplines. The following is a brief description of Toxicology Group members' primary research interests within sub-disciplines of toxicology.
