Dr. Cook is involved in the design, conduct and analysis of several large randomized trials, including the Women's Health Study, the Physicians' Health Study, and the Women's Anti-Oxidant Cardiovascular Study. She leads the Trials of Hypertension Prevention (TOHP) Follow-up Study, an observational follow-up of participants in Phases I and II of TOHP. This study focuses on the long-term effects of weight loss and sodium reduction interventions on subsequent cardiovascular disease, as well as on the observational effects of average sodium intake and intentional weight loss.

Dr. Cook's methodologic interests include the implications of measurement error and missing data, especially non-randomly missing blood pressure data, on longitudinal results. She is also interested in self-selection for exposures, such as use of aspirin, and the implications for causal analysis. In addition, Dr. Cook is involved in predictive modeling of observational data, for detecting gene-gene and gene-environment interactions, as well as for developing risk prediction scores using clinical biomarkers.
