Adam V. Wisnewski PhD

Senior Research Scientist, Occupational Medicine, Yale School of Medicine

Dr. Wisnewski's research focuses on normal and pathogenic responses to occupational and environmental exposure, with an emphasis on isocyanates, a leading cause of occupational asthma. He uses a multi-pronged approach to study fundamental mechanisms of exposure-induced human disease, through bench studies with human tissue samples, clinical studies of “at risk” populations, and in vivo studies in mice to answer questions that cannot be ethically or practically addressed clinically. Specific highlights of his research investigations include (a) structural elucidation of TDI, and other isocyanates, reactivity with human proteins, using pioneering in vitro (vapor phase exposure) approaches, (b) seminal work defining the role of skin in the development of systemic immune hypersensitivity to isocyanate exposure, as well as (c) bioinformatic analyses of isocyanate exposure effects on airway epithelial cells, especially influences on thiol-redox homeostasis and oxidative stress. New immunoassays developed have been used to aid industrial hygiene efforts by the US Air Force (Hill AFB). A particular strength of his research throughout his career has been my focus on trying to understand critical scientific unknowns through direct studies on affected human populations, ranging from parasite/viral-infected patients to chemically exposed workers. His combined experience in clinical research and laboratory skills have prepared me to lead the investiagtion propopsed herein.
