Research Focus

Dr. Maskarinec, a physician in preventive medicine and nutritional epidemiologist, has the goal to contribute to chronic disease prevention by understanding the etiology of breast cancer, Non-Hodgkin Lymphoma (NHL), and type 2 diabetes. To elucidate the difference in health status across ethnic groups, she has performed comparative studies that included participants from Hawaii, Guam, the US, Japan, and Europe. Nutritional risk factors, especially dietary patterns, overweight and obesity, and soy foods are the main topics of numerous publications. In the area of breast cancer risk, she has worked with intermediate endpoints, such as mammographic densities, pathologic markers in tissue, serum hormone levels, urinary estrogen metabolites, adipokines, inflammatory markers, and nipple aspirate fluid. More recently, the role of obesity, dietary patterns, type 2 diabetes, and mammographic density as predictors of cancer survival among participants of the Multiethnic Cohort have yielded interesting findings. Dr. Maskarinec is dedicated to education and training. She leads the Cancer Center's Summer Internship Program for high school and undergraduate students funded by a P30 CURE supplement and regularly teaches at the University of Hawaii and institutions in foreign countries.
