Academic Credentials


Teaching and Clinical Areas

Dr. Janz's position is closely associated with the University of Saskatchewan's Toxicology Centre. He teaches three undergraduate courses (Principles of Toxicology, General Pharmacology, and Toxicology of Industrial Pollutants) and a graduate course (Biochemical Toxicology).


Research Interests

Dr. Janz investigates interactions between physiological control and environmental alteration of developmental and reproductive processes in vertebrates.

The goal is to investigate relationships between biological responses at the molecular and cellular levels with those occurring at the organ, organism and population levels in animals exposed to environmental stressors. This is achieved by combining physiological, cell biological, pharmacological and molecular biological approaches in the laboratory with ecological approaches in the field.

Dr. Janz's recent work has focused on developing non-invasive techniques to measure long-term stress in fish and wildlife species.
