Biography

William Vollmer, PhD, is a biostatistician who conducts research in several areas, including the non-pharmacologic control of blood pressure and weight, and the epidemiology and management of asthma and chronic obstructive pulmonary disease (COPD).

The focus of his more recent research has been on how the electronic medical record can be used with information technology to help improve population-based disease management within Kaiser Permanente. Two such studies were designed to help patients get needed medication refills at the right time. The PEANUT study promoted medication adherence among patients with asthma; the PATIENT study promoted adherence among patients with cardiovascular disease. These trials were conducted in close partnership with the Kaiser Permanente Health Plan and involved thousands of participants in order to provide a real world test of the interventions. Such “pragmatic” studies are an important way to help speed the translation of research findings into clinical practice.

Much of Dr. Vollmer’s work is done in collaboration with other sites, and he has directed or helped to direct a number of data coordinating centers as part of these efforts. In this role, he helps steer multi-site trials and works collaboratively with other investigators to resolve complex protocol-related issues. These collaborative studies included the original work on the Dietary Approaches to Stop Hypertension (DASH) diet, which has since become widely recognized and promoted as an effective, easy to follow dietary pattern to help individuals reduce both blood pressure and weight.

Dr. Vollmer received his PhD in biostatistics from the University of Washington. He is the recipient of a Lifetime Achievement Award from the Behavioral Sciences and Health Services Research Assembly of the American Thoracic Society and is an associate fellow of the American Heart Association's Council on Epidemiology. He has been an invited speaker at a number of national and international scientific conferences, and for many years has traveled the world teaching pulmonary clinicians how to conduct clinical research.
