Professor of Environmental Toxicology, Hokkaido University

Current research:

Ecotoxicology, comparative animal physiology and toxicology. Research subjects are to clarify the effects of environmental pollution on the physiology of wildlife, and to elucidate metabolic pathways and signal cascades of xenobiotics in wild and laboratory animals.

Projects for graduate students:

1. Support for career path activity
2. Publicity activity for the program
3. Promotion of fostering Chemical Hazard Control Expert
4. Global surveillance for chemical hazard/Support for the international activity in the field of chemical hazard
