IHPI Scholars Leadership


Rodney (Rod) A. Hayward, M.D.

Professor, Internal Medicine, Medical School

Hayward received his training in epidemiology, biostatistics and health economics as a Robert Wood Johnson Clinical Scholar at UCLA and at the RAND Corporation, Santa Monica. His research examines measurement of quality, costs, and health status, environmental and educational factors affecting physician practice patterns, quality improvement, and physician decision-making. His work also focuses on quality measurement and improvement for chronic diseases, such as diabetes, hypertension, and heart disease, the use of data from clinical trials to inform clinical practice guidelines, and ways to improve healthcare quality and efficiency through the use of more sophisticated performance measures and market incentives.


Michele Heisler, M.D., M.P.A.

Professor, Internal Medicine, Medical School

Heisler is a research scientist at the VA Center for Clinical Management Research, Ann Arbor HSR&D Center of Innovation. Her research centers on patient self-management of chronic illnesses, patient-doctor relations, and disparities in processes and outcomes in chronic illnesses. Her work also focuses on behavioral interventions and implementation research, with emphases on looking at health system design and ways to enable peer support and create better linkages between primary care and community resources. She is also deeply interested in issues of health and human rights.

Patricia Hurn, Ph.D., R.N., FAAN

Dean & Professor, Nursing, School of Nursing

Hurn's leadership work focuses on collaborative bio-health research models, science education innovation and research technologies. She is an internationally recognized researcher on stroke and other neurological conditions and directs an interdisciplinary research laboratory that conducts biomedical research and applies findings to point-of-care patient applications. She joined UMSN from the University of Texas System, where she was vice chancellor for research and innovation and executive officer.

Theodore (Jack) J. Iwashyna, M.D., Ph.D.

Associate Professor, Internal Medicine, Medical School

Iwashyna's research focuses on the organization of critical care services to provide high quality and value and improved outcomes. Iwashyna work seeks to understand the context of critical illness (and severe sepsis in particular), both in how critical illness influences a patient’s life course, and in how the organizational environment influences the effectiveness of the care that a patient receives. His research interests also include health system organization, evaluating hospital quality of care, and medical education.

Janet Larson, Ph.D., R.N., FAAN

Professor, Nursing, School of Nursing

Larson is professor and chair of the Department of Health Behavior and Biological Sciences at the School of Nursing. She is an expert in the pulmonary rehabilitation of people with chronic obstructive pulmonary disease (COPD). She maintains an active program of research, studying factors that influence symptoms, physical activity, and quality of life for people with COPD. Most of her research focuses on exercise interventions for people with COPD and includes a series of studies to examine the effects of inspiratory muscle training and cycle ergometry training. In the past, Larson has conducted a prospective longitudinal study to examine factors that influence deterioration of respiratory muscle strength and functional status in people with COPD. More recently, she completed a randomized controlled trial of upper body strength training with a self-efficacy enhancing intervention to promote exercise adherence in people with COPD.

Caroline Richardson, M.D.

Professor, Family Medicine, Medical School

Dr. Richardson is a physical activity researcher who emphasizes the importance of using low-cost and scalable approaches to promoting physical activity. Her research focuses on physical activity and its effects on chronic diseases, web-based health interventions, diabetes, quality improvement, heart disease risk factor modification, and veterans’ health. 

Senior Associate Directors

Joel Howell, M.D., Ph.D.

Professor, Internal Medicine, Medical School

Dr. Howell has written widely on the use of medical technology, examining the appropriateness of its use, the social and contextual factors relevant to its clinical application and diffusion, and analyzing why American medicine has become obsessed with its use. His research attempts to analyze the implication for health policy of factors that have both contributed to and slowed the diffusion of medical technology into clinical practice, using both a sociology of knowledge and a comparative approach.

Laurence (Larry) F. McMahon, M.D., M.P.H.

Professor, Internal Medicine, Medical School

Dr. McMahon's research is focused in the area of small area variation in the use of hospital and health services, with particular attention to differences in care delivered to sociodemographic and racially diverse segments of our society. In addition, he has continued to develop systems to measure and manage hospital-based practices, focusing on both utilization and the quality of care.
