She is a founding staff member of ICAP’s Harlem Prevention Center and supports ICAP’s community-based prevention efforts in sub-Saharan Africa. She holds a PhD from the State University of New York at Stony Brook.

M. Claire Greene, Assistant Professor of Population and Family Health

M. Claire Greene is a psychiatric and substance use epidemiologist in the Program on Forced Migration and Health. Her research focuses on improving the effectiveness and implementation of mental health and psychosocial support programs in humanitarian settings. She develops, evaluates, and scales-up interventions in diverse settings and populations globally, in collaboration with governmental and non-governmental organizations, international agencies, and academic institutions. She co-teaches “Investigative Methods in Complex Emergencies.” She received her PhD from Johns Hopkins Bloomberg School of Public Health.

Michael Joseph, Vice Dean for Education and Associate Professor of Epidemiology

Michael Joseph is a highly regarded teacher and curricular innovator with a record of expanding access to public health education to improve equity in the field. As Vice Dean for Academic and Student Affairs and associate professor of epidemiology and biostatistics at SUNY Downstate School of Public Health, Joseph helped drive a substantial increase in enrollment, including Black, Latinx, and first-generation college students. In 2013, he was recognized with the SUNY Chancellor’s Award for Excellence in Teaching. His research has focused on HIV transmission risks among heterosexual Black men. He received his PhD from the University of Michigan. (Read more about Joseph here.)

Alison Kupsco, Assistant Professor of Environmental Health Sciences

Allison Kupsco is an environmental toxicologist and epidemiologist whose doctoral research in fish models focused on molecular processes triggered by environmental exposures, including flame retardants, selenium, and climate change. Now working as an epidemiologist, her research centers around epigenetic biomarkers for children’s environmental health, including examining the effects of prenatal exposures to flame retardants on childhood obesity via the mitochondria. She earned a PhD from the University of California-Riverside and completed a post-doc at Columbia Mailman under Andrea Baccarelli.  

Adana Llanos, Associate Professor of Epidemiology

Adana Llanos is a molecular epidemiologist whose research focuses on the molecular factors and sociobiologic mechanisms that cause cancer disparities. Her research seeks to address cancer outcomes disparities, through collaborative studies that center on cancers that disproportionately affect minority and medically underserved populations. She also focuses on cancer epidemiology and surveillance in populations of African ancestry by subgroups based on birthplace. Previously, she was an assistant professor of epidemiology at Rutgers School of Public Health. She holds a PhD from Howard University.

Kate Lovero, Assistant Professor of Sociomedical Sciences

Kate Lovero focuses on improving adolescent mental health in low-resource settings. Currently, she is collaborating with the Mozambican Ministry of Health to develop services for adolescent depression and anxiety. She is also beginning work on training primary care providers in Mozambique to screen and provide an intervention for adolescents with suicide risk. Previously, she was a NIH Global Health Equity Scholar and Fulbright Postdoctoral Fellow in Brazil. She earned her PhD in Neuroscience from the University of California, San Francisco.

Nour Makarem, Assistant Professor of Epidemiology

Nour Makarem pursues research at the intersection of preventive cardiology, sleep and circadian science, nutrition, and epigenetics. Her research addresses the role of sleep, diet, and rest-activity patterns in cardiovascular risk. Additionally, she examines the influence of health behaviors on epigenetic mechanisms related to aging that can alter susceptibility to heart disease. Her goal is to improve risk prediction and inform precision behavioral interventions to promote cardiovascular health equity, particularly among immigrant populations. She earned her PhD from New York University.

Sen Pei, Assistant Professor of Environmental Health Sciences

Sen Pei studies transmission dynamics of infectious diseases using mathematical models and computational tools. His recent studies focus on the spatial spread of influenza, dengue, and COVID-19, as well as the transmission of antimicrobial-resistant pathogens in health care systems. His goal is to better understand the environmental, social, and ecological drivers of disease transmission, to improve surveillance, forecasting, and control of infectious outbreaks. Previously, he served as a research scientist in Jeffrey Shaman’s lab. He earned his PhD from Beihang University in China.
