Division of Chemical Toxicology

The mission of the Division is to improve human health and public welfare by promoting the understanding of chemical mechanisms that govern disease processes and the toxicity of drugs, environmental agents, and endogenous chemicals. This will be accomplished by (1) providing a forum for communicating research in the field of chemical toxicology; (2) encouraging further research into chemical mechanisms of toxicity; (3) providing a rigorous scientific basis for risk assessment; (4) providing continuing education, leadership training, and career development opportunities for our fellow chemists; and (5) sponsoring with other societies and divisions, symposia and other programs of mutual interest.

Huiwang Ai
Huiwang Ai

Huiwang Ai, of the University of California, Riverside has won the sixth annual Chemical Research in Toxicology -Young Investigators Award.  He joins past winners Yinsheng Wang,   Dean Naisbitt, Shana Sturla, Penny Beuning, and Yimon Aye.

Huiwang Ai’s  research  focuses on the engineering of novel molecular probes to peer
into cells and brains to understand their communications. He uses a collection of innovative techniques, such as protein engineering and fluorescence and bioluminescence imaging, to dissect signaling pathways involving redox-active molecules, neuromodulators, and protein post-translational modifications.

Huiwang will receive his award at a symposium during the Division of Chemical Toxicology Program at the American Chemical Society’s National Meeting this August in Washington DC.

blair-ia-photo-2014Ian A. Blair has won the 2017 Founders’ Award from the Division of Chemical Toxicology of the American Chemical Society.  Dr Blair has made outstanding contributions to the field of Chemical Toxicology.  He has pioneered the use of mass spectrometry to identify biomarkers for carcinogenesis, cardiovascular disease, and neurodegeneration.  He developed  electron capture atmospheric pressure chemical ionization, which makes it possible to conduct quantitative analyses on chiral biomolecules. See his current research interests on his lab website.  Also read an interview from Francesca Lake in Future Science OA.

Dr Blair will receive the Award, during a Symposium, in his honor, in August at the American Chemicals Society’s National Meeting
