A Professor of Medicine, Dr. Weiner joined the IU School of Medicine faculty and the Regenstrief Institute in 1999, following undergraduate work at Brown University, medical school at Duke University, and residency and fellowship at The Johns Hopkins  University. While at Hopkins, he also earned a master’s degree in public health. He is Director of Regenstrief Institute's William M. Tierney Center for Health Services Research and the Indiana University Center for Health Services and Outcomes Research. He also directs the Center for Health Information and Communication, a Center of Innovation in the Department of Veterans Affairs Health Services Research and Development Service, located at the Richard L. Roudebush VA Medical Center in Indianapolis.

Dr. Weiner’s professional interests are health services research, geriatrics, and health informatics. At IU Geriatrics, he founded the gero-informatics program, which under his leadership focused on leveraging health information technologies to improve the care of older  adults.  In 2003, Dr. Weiner was awarded the Outstanding Researcher Award from the Division of General Internal Medicine & Geriatrics, Indiana University School of Medicine. His clinical and health-services research is focused on measuring and improving the quality, coordination, and delivery of health services for older adults. He also studies the effects of health  information and information technology on physicians' practices and patients' outcomes. Dr. Weiner has conducted studies of specialty referral, patient-physician videoconferencing, and other forms of telecommunication to improve healthcare. Current research includes development, implementation, and study of information systems to promote  clinical handoffs, management of medications, patient-centered  geriatrics care, and clinical decision support.

In 2013, Dr. Weiner received the Indiana University Department of Medicine Teaching Excellence Award. He serves on the Board of Directors for the Center for Health Innovation and Implementation Science in the IU School of Medicine and on the Project Development Team in Implementation Science for the Indiana Clinical and Translational Sciences Institute.

"Use of Electronic Medical Records for Observational Assessment of Healthcare Utilization among Adults with Chronic Cough in Central Indiana"
2017-2018, Co-Principal Investigator (with Jessica Weaver, Merck)
Solicitation: Merck/Regenstrief Program in Personalized Health Care Research and Innovation
Research & Technical Area: health services and outcomes research
Aims: Defining a cohort of patients with chronic cough, and determining which of them use the most health care services and have relevant comorbidity and other characteristics, are important needs for advancement of the care of these patients. The aims of this collaborative project are:
