Research: Margaret Karagas conducts epidemiologic studies of human malignancies, in particular non-melanoma and melanoma skin cancers, bladder cancer and large bowel neoplasms. She is examining the effects of exposure to toxic metals in drinking water, exogenous and endogenous female sex steroids and the sources of ionizing and non-ionizing radiation. She is also involved in a regional study to understand the excess mortality rates in bladder cancer in Maine, New Hampshire and Vermont. Her work is interdisciplinary, and her studies consider exposure, biologic markers, genetic susceptibility, tumor characteristics, intermediary endpoints and novel statistical approaches.
