Research Focus

Dr. Merritt's research utilizes epidemiological studies to evaluate risk factors for women's cancers with a focus on gynecologic (ovarian and endometrial) cancers. Her goal is to develop better strategies for their prevention. She also hopes to improve the health of women diagnosed with gynecologic cancers by studying modifiable factors that may influence survival following a cancer diagnosis.

Dr. Merritt has led studies to investigate diet, reproductive factors, metabolic and obesity-related factors and medication use in relation to cancer risk and/or survival using data from several epidemiological cohort studies. She has also trained extensively in molecular biology and she conducts studies to evaluate the molecular mechanisms that underlie established risk factor-disease associations and mechanisms that may explain differences in disease outcomes.

One of her current research interests is to evaluate how modifiable lifestyle factors may contribute to differences in ovarian and endometrial cancer incidence and mortality rates across racial/ethnic groups using the resources available in the Multiethnic Cohort (MEC) Study. She is also investigating how dietary factors may be associated with different body fat distribution subtypes (e.g., accumulation of abdominal fat) in the MEC Body Composition Study.
