Latinx Health Research Group

Brown University School of Public Health has a budding body of research focused on improving Hispanic/Latinx health related to both chronic and infectious diseases. Our faculty research has focused on improving health and wellness outcomes related to diet and physical activity, healthy aging, and reducing HIV infections among Hispanic/Latinx populations. The following faculty members have active research grants related to improving Hispanic health.

Jasjit S. Ahluwalia, MD, MPH, MS

Professor of Behavioral and Social Sciences, Professor of Medicine

Dr. Ahluwalia’s primary research has focused on nicotine addiction and smoking cessation in African-American smokers. His work has extended to harm reduction with the use of e-cigarettes in Latinx and African American combustible tobacco users. He also has a broad interest in minority health, health disparities, and the social determinants of health.

Research Profile

Tanya J. Benitez, PhD, MSW

Assistant Professor of Behavioral and Social Sciences

Dr. Benitez’s research focuses on Latina women’s health and disease risk reduction behavior, especially in the realm of physical activity promotion.

Research Profile

Katie B. Biello, PhD

Associate Professor of Behavioral and Social Sciences, Associate Professor of Epidemiology

Dr. Biello’s research interests include identifying and understanding the underlying risk factors for social inequities in HIV/STIs and developing behavioral interventions to reduce risk among racial, sexual and gender minorities and those in resource limited settings, both domestically and globally.

Research Profile

Suzanne M. Colby, PhD

Professor of Psychiatry and Human Behavior, Professor of Behavioral and Social Sciences

Dr. Colby has expertise in developing and testing brief motivational interventions (MIs) for alcohol and tobacco use. Over the past 15 years, she has collaborated with Dr. Christina S. Lee (lead investigator) on a line of research investigating alcohol-related health disparities among Latinx heavy drinkers.  The initial work involved formative research exploring risk and protective factors related to alcohol use among Latinx drinkers such as minority stress (e.g., due to acculturation stress, discrimination). The next phase was a pilot randomized controlled trial that supported the feasibility and acceptability of a culturally-adapted motivational intervention (CAMI) for Latinx drinkers. This was followed by a fully powered RCT, which demonstrated the benefits of CAMI over standard MI for Latinx drinkers who either were less acculturated or experienced higher levels of discrimination at baseline. We are also conducting a study (with Dr. Molly Magill) of the therapeutic mechanisms that account for the differential benefits of CAMI in Latinx drinkers.  

Research Profile

Akilah Dulin, PhD

Assistant Professor of Behavioral and Social Sciences

Dr. Dulin Keita has two primary research foci that include examining (1) risk factors and resilience resources related to cardiovascular disease (CVD) risk (e.g., diet, physical activity, obesity) and (2) HIV outcomes among children and racial/ethnic minorities.

Research Profile

Kim Gans, PhD, MPH

Adjunct Professor of Behavioral and Social Sciences

Dr. Gans’ research includes intervention development and evaluation research in community-based settings to improve eating habits and prevent obesity. The majority of her research has been with ethnic minority, low income and/or low literate populations and an emphasis of her work has been innovative health communication technologies including theory-based tailored print and video interventions using computerized expert systems.

Research Profile

Barton M. Laws, PhD

Assistant Professor of Health Services, Policy and Practice

Dr. Laws is medical sociologist with a particular interest in people's experience of health and illness and of medical services; and provider-patient relationships and communication. The long-term goal of his research is to support the continuing transformation of medicine and health care more broadly into an institution built around patients' needs: physical, psychological, and social.

Research Profile

Bess H. Marcus, PhD

Dean of School of Public Health, Professor of Behavioral and Social Sciences

Dr. Marcus is a clinical health psychologist whose primary research interests are in the prevention of cardiovascular disease and the promotion of women's health. She has spent over 25 years conducting research primarily on physical activity behavior and has developed a series of assessment instruments to measure psychosocial mediators of physical activity behavior as well as low-cost interventions to promote physical activity behavior in community, workplace, and primary care settings.

Research Profile

Matthew J. Mimiaga, ScD, MPH

Professor of Behavioral and Social Sciences, Professor of Epidemiology, Professor of Psychiatry and Human Behavior

Dr. Mimiaga’s research program focuses on interventions to decrease sexual risk in HIV primary and secondary prevention; biobehavioral interventions to enhance antiretroviral medication uptake and adherence; psychosocial treatment interventions for stimulant use disorder and concurrent HIV risk; infectious disease and psychiatric epidemiology; and global health research

Research Profile

Amy S. Nunn, ScD, MS

Associate Professor of Behavioral and Social Sciences, Associate Professor of Medicine

Dr. Nunn conducts applied research on how to reduce racial and ethnic disparities in HIV infection, treatment and care, and is known for her innovative community partnerships to address disparities, including engaging clergy and community leaders in HIV testing, treatment and social marketing campaigns.

Research Profile

Don Operario, PhD

Associate Dean for Academic Affairs, Professor of Behavioral and Social Sciences

Dr. Operario is committed to research that addresses health inequities in the United States and in international settings. His current research involves developing and testing psychosocial and community-based health interventions for reducing HIV transmission, as well as other mixed methods research aiming to understand the determinants of psychological and behavioral health in racial/ethnic minority populations and sexual and gender minority populations. 

Research Profile

Patricia Risica, DrPH

Associate Professor of Behavioral and Social Sciences, Associate Professor of Epidemiology

 

Professor Risica's research interests include obesity, nutritional epidemiology and eating behaviors; the influence of location of fat on the body with disease risk; breastfeeding; and diabetes, smoking cessation and avoidance of environmental tobacco smoke, heart disease and obesity, and early detection of melanoma. Her research interests encompass many aspects of intervention development and assessment of interventions in practical, community settings.

Research Profile

Maricruz Rivera-Hernandez, PhD

Assistant Professor of Health Services, Policy and Practice

Dr. Rivera-Hernandez’s research interests include racial and ethnic disparities in access to and quality of care, and health outcomes of older adults. Her specific research focus is on health disparities and healthcare issues of elderly Hispanics.

Research Profile

Jacob J. van den Berg, PhD, MS

Assistant Professor of Behavioral and Social Sciences, Assistant Professor of Medicine

Dr. van den Berg's research focuses on the development, implementation, and evaluation of community-based behavioral and biomedical health interventions for underserved and marginalized groups. He is particularly interested in advancing the integration of health informatics (eHealth/mHealth) and biobehavioral strategies for preventing HIV/STIs and substance use among racial/ethnic and sexual and gender minority populations.
