Monika M Safford, M.D.

Dr. Safford is a health equity researcher with a focus on eliminating disparities in health outcomes for individuals with cardiometabolic diseases such as diabetes, especially focused on vulnerable and high-risk populations. She has led four community-engaged behavioral interventional trials that together recruited over 2500 low-income Black residents of the rural Southeast to improve their self-management of diabetes or high blood pressure. She has a large observational research program funded by NHLBI centered around the REasons for Geographic and Racial Differences in Stroke (REGARDS) study. This national cohort study of over 30,000 Black and White community-dwelling Americans was the first study to describe racial differences in urinary protein as a risk factor for stroke and heart attack; atrial fibrillation as a risk factor for heart attack; continued racial disparities in the risks of heart attack and especially death at presentation with heart disease; the harms of the Southern diet; and risks conferred by depressive symptoms and stress, among many others. Students and trainees are welcome to propose studies and work with experienced scientists to produce rigorous observational research using these data.

At Weill Cornell, Dr. Safford was co-PI on Cornell’s HRSA-funded Diversity Center of Excellence that led to the HRSA-funded T32 training program called the Cornell-Hunter Health Equity Research Fellowship. She is the chief architect of the Patient Activated Learning System, a novel user-driven information system specifically designed for people with low health literacy that is challenging the paradigm that “education alone is not enough to change behavior.”

Dr. Safford founded, is an academic member of, and continues to co-lead the university-wide Cornell Center for Health Equity that now includes over 400 members from the Cornell academic community as well as community partners.

Christopher Gonzalez, M.D., MSc

Dr. Gonzalez’s research aims to understand and leverage social and cultural behaviors to improve the health of diverse Hispanic populations in the United States. Through ongoing collaborations with investigators of the national Hispanic Community Health Study/Study of Latinos (SOL), the Duke Network Analysis Center (DNAC), and New York Regional Center for Diabetes Translation Research (NY-CDTR), he has explored the heterogeneity of health behaviors and health outcomes of the Hispanic population, with a specific focus on understanding the roles of migration, acculturation and social networks. His research predominantly assesses how these factors relate to inequities in cardiometabolic health, including obesity and diabetes prevention, but has also assessed their relation to COVID-19 and Hepatitis C. Dr. Gonzalez is funded by the National Institute for the Diabetes and Digestive and Kidney Diseases, and his research is informed by his practice of primary care in a federally qualified health center in a predominantly Hispanic community in New York City.

Margaret McNairy, M.D.

A physician-scientist focused on improving health care in resource-poor populations in Haiti and Africa, particularly for HIV and cardiovascular diseases. Dr. McNairy's HIV research focuses on developing effective and practical models of care, which will reduce HIV-related mortality and decrease HIV transmission at the population level. She also evaluates cardiovascular disease risk factors and other chronic diseases in both HIV-infected and uninfected populations to understand the determinants of chronic diseases in these populations.

Dr. Iris Y Navarro Millan

Iris Y Navarro Millan, M.D.

Dr. Navarro-Millán’s research focuses on factors that influence outcomes, particularly in cardiovascular (CV) disease among patients with rheumatoid arthritis (RA). The goals of this research portfolio aims to develop and implement evidence-based behavioral interventions for patients with RA with a specific target on CV risk reduction, diet, and exercise. The primary method to deliver these interventions is via the internet, which allows for a larger reach to patients, enhanced by the facilitation from peer coaches. Peer coaches are individuals who themselves have either RA or osteoarthritis and are trained to provide support to participants of these interventions. They guide participants to maximize the benefits they can obtain from these interventions. Other areas of Dr. Navarro-Millán’s work are in examining factors that affect morbidity and disability in patients with arthritis.

Dr. Navarro-Millán is an academic member of the Cornell Center for Health Equity.

David Scales, M.D., PhD

As a hospitalist and sociologist, Dr. Scales' research interests lie at the intersection of medicine and social science. His current is focus on medical communication, for example, between patients and healthcare professionals or medical researchers to the public, which has led him to study the positive care effect (aka placebo) and medical misinformation. In collaboration with researchers at the Annenberg Public Policy Center at the University of Pennsylvania and Critica, an NGO, he has trained "infodemiologists" as science communication professionals to help push back against medical misinformation and build Covid-19 vaccine confidence in online communities, leveraging cross-disciplinary evaluation methodologies that provide insight into complex systems.

Martin Shapiro, M.D., CM, PhD

Dr. Shapiro is an accomplished health services researcher. His scholarship has largely focused upon access to care and disparities in health. His most prominent work has been the HIV Cost and Service Utilization Study (HCSUS), which enrolled a national probability sample of persons with HIV and has been widely-recognized for affecting policy in HIV care through studies of access, diffusion of innovation, costs and utilization, mental health, drug use, risk behavior, viral resistance, health outcomes, providers of HIV care, and the impact of the Ryan White Care Act on patterns of care for HIV. He also has studied racial/ethnic and socioeconomic influences on patterns of care, the impact of major diseases on disparities in life expectancy, the impact of copayments on access to care, scientific misconduct in investigational drug trials, patterns of scientific authorship and their appropriateness in the biomedical literature, the quality of pharmaceutical advertising, variations in the use of intensive care, attitudes of physicians to the care of persons with HIV, and appropriateness of patterns of laboratory testing in clinical care.
