Dr. Theresa Coles
Assistant Professor in Population Health Sciences

Dr. Coles is an Assistant Professor in Population Health Sciences. She specializes in the development and psychometric evaluation (reliability, validity, responsiveness, and responder thresholds) of patient-reported outcome measures and other clinical outcomes assessments. Her research interests include evaluating COA measures in clinical practice, improving the interpretability of COAs (e.g., responder thresholds, minimal important change), and facilitating patient-provider communication using patient-reported outcome measures.

Dr. Coles received her PhD in Health Policy and Management (decision sciences and outcomes research) from the University of North Carolina at Chapel Hill in 2017. Prior to joining the Duke faculty in 2018, Dr. Coles worked in the Patient-Centered Outcomes Assessment group at RTI Health Solutions for almost 10 years, where she developed and evaluated COA measures for use in clinical trials and clinical practice.

A social scientist by training, Dr. Corneli has over two decades of experience conducting qualitative, formative, and mixed-method studies in multiple countries worldwide, primarily in biomedical HIV prevention and bioethics. A significant portion of her research portfolio has focused on engaging patients/participants and other key stakeholders in qualitative research to inform clinical studies; socio-behavioral interventions, programs, and policies; and material and scale/questionnaire development. Her HIV-related research focuses on identifying evidence-based strategies for linking populations who could benefit from pre-exposure prophylaxis (PrEP) to PrEP care, for supporting PrEP adherence to achieve protective levels, and for keeping clients engaged in PrEP care for as long as their HIV risk persists. Her bioethics research focuses primarily on informed consent and functioning of ethics review boards.

Dr. Corneli received her PhD in Health Behavior from UNC Chapel Hill, with a minor in Anthropology, and her MPH in International Health from Emory University.

Juan Marcos Gonzalez, PhD
Assistant Professor in Population Health Sciences

Dr. Gonzalez is an Assistant Professor in the Department of Population Health Sciences. He is an expert in the design of stated-preference survey instruments and the use of advanced statistical tools to analyze stated-preference data. His research has focused on the transparency in benefit-risk evaluations of medical interventions, and the elicitation of health preferences from multiple stakeholders to support shared decision making.

Dr. Gonzalez co-led the first FDA-sponsored preference study which was highlighted in the FDA’s recent precedent-setting guidance for submitting patient-preference evidence to inform regulatory benefit-risk evaluations of new medical devices. More recently, he collaborated with the Medical Devices Innovation Consortium (MDIC) to prepare the first catalog of preference-elicitation methods (part of the Patient-Centered Benefit-Risk Assessment Framework) suitable for benefit-risk assessments of medical devices. As a core group member of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Conjoint Analysis Task Force, Dr. Gonzalez helped draft good-practice recommendations for statistical analysis, interpretation, and reporting of health preference data. Currently, he is working with the Center for Devices and Radiological Health at FDA to support the development of the Center’s capabilities for the review of stated-preference data in regulatory decisions.

F. Reed Johnson, PhD
Professor in Population Health Sciences

Dr. Johnson, has more than 40 years of academic and research experience in health and environmental economics. He led the first FDA­ sponsored study that measured a patients’ willingness to accept benefit-risk tradeoffs for new health technologies which concluded in FDA guidance on submitting patient-preference data to support regulatory reviews of medical devices. He also designed and analyzed numerous surveys that measure preferences of health risk reductions, improved environmental quality, and the value of health outcomes. Currently Dr. Johnson’s research involves quantifying the patients’ willingness to accept side ­effect risks in return for therapeutic benefits and estimating the general time equivalences among health states.

Dr. Johnson is a Professor in the Department of Population Health Sciences who has published in over 140 books and peer-reviewed journals including the Review of Economics and Statistics, Journal of Health Economics, Medical Decision Making, Health Economics, Value in Health, and the Journal of Policy Analysis and Management
