Dr. Engel's main research interests are in environmental and occupational risk factors for cancer and the role of genetic susceptibility. Dr. Engel is the Principal Investigator of a study examining the relationship of blood levels of organochlorines and aflatoxins with the risk of primary liver cancer. He is also Principal Investigator of studies of breast cancer risk within a large agricultural cohort; he is currently examining pesticide exposures as well as sun exposure and genetic variation in the vitamin D pathway. In addition, he is conducting a study of the association between germline genetic polymorphisms and genetic mutations in tumors among patients with rare gastrointestinal stromal tumors. He continues to collaborate with colleagues at the National Cancer Institute, the Centers for Disease Control, and the Norwegian Cancer Registry on a study of serum organochlorine levels and risk of selected cancers.
