Professional Interests:
Professor Karagas' research encompasses several epidemiological studies focusing on the etiology and prevention of human cancers, as well as adverse pregnancy and children's health outcomes. These include investigations to determine incidence rates of basal cell and squamous cell skin cancer for a geographically defined US population, and to assess the extent of any increase over the past 20 years. Another aspect of this research is a case-control study of these malignancies to identify risks associated with emerging exposures such as indoor tanning, ingestion of arsenic-containing drinking water and foods, immunosuppressive therapies and other factors. This research has been extended to bladder cancer. One of her current initiatives involves establishing a cohort of pregnant women in New Hampshire to assess the potential impact of arsenic and other exposures on risk of maternal and child health. Her ongoing work further includes studies of melanoma in women and collaborative investigations of exposure biomarkers, individual susceptibility, and biological response to environmental agents. Professor Karagas is one of the Principal Investigators of a NCI-funded cross-disciplinary postdoctoral training grant, serves as a mentor for early career investigators and participates in a variety of courses at the undergraduate and graduate level.
