Led the first study showing that celecoxib, a nonsteroidal anti-inflammatory drug, reduces both the size and number of polyps in patients with familial adenomatous polyposis, an inherited disorder that predisposes gene carriers to colorectal cancer; this finding led to approval by the FDA of celecoxib as a pharmacologic treatment in the management of this condition.

Showed that the presence of some forms of the receptor for dopamine, an important signaling molecule in the brain, can identify persons at higher risk for addiction to nicotine and may be associated with reduced ability to quit smoking and poor response to antidepressant therapy.

Demonstrated the stronger genetic effect on lung cancer risk of specific nicotinic receptors among ever-smoking African-Americans than has been observed in Caucasians. Also showed that the genetic effects of this region affect both lung cancer and smoking behavior, with the stronger effect being on lung cancer risk.
