Adam Atherly, Ph.D.
Director of the Health Services Research Center
Professor of Medicine at the Larner College of Medicine

Adam Atherly An expert in health economics and the economics of aging and consumer decisions regarding health plan choice, Dr. Atherly holds a Ph.D. in health services research, policy and administration from the University of Minnesota, and an M.A. in economics from the University of Washington.He joined the Colorado School of Public Health as associate professor and founding chair of the Department of Health Systems, Management and Policy in 2009 and was promoted to full professor in 2016. Consistently funded since 2002 by such agencies as the Centers for Disease Control and Prevention, Agency for Healthcare Research and Quality, NIH, Centers for Medicare and Medicaid Services and the Robert Wood Johnson Foundation, Atherly’s research targets health economics, with an emphasis on the economics of aging and consumer decisions regarding health plan choice. His research spans numerous methodological and topical areas, including healthcare spending and expenditure modeling, scale development and psychometric analysis, evaluation of efforts to improve quality of care and patient safety and cost-effectiveness analysis.  He is the author of more than 70 journal articles and book chapters and has presented his work at more than 75 national professional meetings. 


Eline van den Broek-Altenburg, Ph.D.
Assistant Professor with the Health Services Research Center

Eline Altenburg Headshot NewDr. van den Broek-Altenburg is an Assistant Professor with the Center for Health Services Research at the University of Vermont College of Medicine. She holds a Ph.D. in Health Services Research with a focus on Economics and Biostatistics from the University of Colorado, a MS degree in Health Services Research & Policy (2014) from Emory University and a MA degree in Political Science (2003) from Leiden University. Her research focuses on patient choice and modelling decisions in healthcare using advanced econometric models and machine learning. She is particularly interested in value-based healthcare from the patient perspective, consumer decisions in health insurance markets, and the effects of decisions and policy reforms on healthcare expenditures. Dr. van den Broek-Altenburg has extensive experience estimating healthcare spending and she has made contributions in further developing standardized quantitative measures to compare health systems and assess health system performance.

In Vermont, she has a specific interest in evaluating the effects of recent payment reforms and analyzing patient decisions to predict demand for new health services in the value based context. With fifteen years of experience in health policy and health economics, her aim is to keep providing timely examples of health policy innovation.

In 2005, Dr. van den Broek-Altenburg founded a think tank in The Hague and served as its director until 2017, in charge of its research agenda and winning grants from public and private organizations. Between 2003 and 2012, she also worked as a health policy fellow with leading think tanks and research institutes in the U.S. and Europe; she has been a health policy adviser in the Dutch and European Parliaments; and she worked as an investigative journalist. Dr. van den Broek-Altenburg contributed to the public debate by publishing scholarly papers and op-eds, and she was frequently seen and heard in the media. In 2012, she went back to academia and has since won several awards and grants for her research, including Academy Health’s Alice S. Hersh Scholarship which recognizes scholars with commitment to the field of health services research and potential to contribute to health policy.

Sarah Nowak, Ph.D.                                 

Assistant Professor of Pathology, Center for Health Services Research

Dr. Nowak is a core member of the center’s research team, as well as an Assistant Professor in the Department of Pathology and Laboratory medicine. Dr. Nowak completed her undergraduate degree in Physics at MIT, and went on to earn a Ph.D. in Biomathematics from UCLA. Before moving to Vermont she was a Senior Information Scientist at the RAND Corporation, where she spent a decade applying mathematical simulation approaches to policy research questions. Specifically, her work focused on using the RAND COMPARE microsimulation model to evaluate health insurance reforms including assessing the impact of the Affordable Care Act on individual and family spending. Also during her tenure at RAND she was one of the founding co-directors for RAND’s Center for Scalable Computing Analysis (SCAN). In this role she guided the center in its mission to examine the use of un-curated data, including social media data, in social and economic research. While at RAND, and continuing on to her time here at UVM, Dr. Nowak has been funded by the NIH for her ongoing examination of the impact of patient and provider social networks on preventive health behavior. This work integrates Dr. Nowak’s expertise in mathematical modeling with national surveys to study how information individuals gather through their social networks impact individual-level decision making as well as health outcomes at the population level. She is also interested in transitioning this work to support the push towards value-based care, and implementing policies that lead to the reduction in the use of low-value services.
