My research sits at the intersection of health policy, health services research, and health informatics. I study the role of health information technology in support of delivery and payment reform efforts; the impact of regulations on health IT innovation, adoption, and use; and specialize in the use of system-generated log data to increase our understanding of health IT’s impact on care quality. My current research focuses on sources of IT-based burden and organizational strategies to reduce that burden. My work has been published in peer-reviewed journals including Health Affairs, JAMA Internal Medicine, Annals of Internal Medicine, the American Journal of Managed Care, the Journal of General Internal Medicine, and the Journal of the American Medical Informatics Association.

Dr. Boudreaux conducts research in interrelated areas of health policy. He is especially interested in public programs for low-income populations and their effects on health and economic well-being. He is also passionate about mentoring health policy and health services researchers and supports the health services educational initiatives within the Center for Population Health.
Dr. Jie Chen is a Professor and Chair of the Department of Health Policy and Management at the University of Maryland School of Public Health. She also directs the Center on Aging at the University of Maryland, College Park, a leading research hub focused on healthcare systems, public health, economics, and whole-person care to promote aging health and well-being.
Dr. Chen’s research focuses on improving care for aging populations with complex needs. She works to find the best ways to connect healthcare, community, and public health systems. Her studies have shown that new care models, such as health information technology and public health partnerships, can improve care coordination, improve care quality, and reduce disparities across racial, ethnic, and geographic groups, especially for the aging population with complex health needs. With 22 years of experience working with large datasets and insurance claims data, Dr. Chen has developed advanced research methods. She has published over 200 peer-reviewed papers and book chapters in the field.
