The division has been one of the key-laboratories responsible for biological safety researches and testings for a variety of chemicals including household products, food & food-additives including GM products, health food, supplements, pesticides/herbicides and pharmaceuticals. On top of the traditional toxicology studies, our current priority issues are the integrated life sciences for the neuro-immuno-endocrine system, as well as developmental biology/morphogenesis, and new technical developments such as the genetically-manipulated recombinant mice, the in vitro alternative methods, the establishment of Toxicogenomics for the future predictive toxicology and other new issues including nanomaterial toxicity.
