Diane J. Catellier has more than 20 years of experience in collaborative research and coordination of large-scale public health studies. She has been principal investigator (PI) for the coordinating centers for five multisite clinical trials and four prospective cohort studies funded by the National Heart, Lung, and Blood Institute (NHLBI). In this role, she has contributed to the design, implementation (data management and monitoring), analysis, and publication of study data. She is currently PI for the Clinical Trials Development Resource for Hematologic Disorders, which provides assistance to investigators supported by the NHLBI to develop clinical trials to test new therapies for hematologic disorders, and engaged in two nutrition-related studies—one which will provide data on feeding patterns of U.S. infants, toddlers, and preschoolers and another which will evaluate the effectiveness of campaigns to increase child access to and participation in federal nutrition programs on child hunger.

Dr. Catellier has helped develop and evaluate interventions for treatment of depression in cardiac patients and treatment of schizophrenia or metabolic disorders associated with use of antipsychotic medications for treatment of the disease and to increase physical activity in children and adolescents. She has been involved in exploring risk factors for heart disease, heart failure, stroke, and cognitive impairment and the impact of acculturation on the health among U.S. Hispanics in two NHLBI-sponsored cohort studies. She has also helped design and implement an evaluation of Centers for Disease Control and Prevention-supported community-based public health prevention and control programs using data from existing surveillance systems and primary data collection efforts.
