My laboratory focuses on understanding mechanisms of carcinogenesis, with emphasis on the role of DNA damage and repair. During the last few years, we have developed ultra-sensitive and highly specific mass spectrometry methods for measuring the DNA and hemoglobin adducts of vinyl chloride, crotonaldehyde, ethylene oxide, propylene oxide, styrene oxide, butadiene, malondialdehyde, cis-platin and O6-methyldeoxy-guanosine, as well as slotblot methods for AP sites and oxidative DNA damage. These methods have been applied to understanding critical mechanisms in carcinogenesis, as well as undertaking molecular epidemiology studies of workers in the butadiene and reinforced plastics industries. We are also examining changes in gene expression associated with oxidative stress and environmental chemical exposure.
