Allison Aiello, PhD
Professor, Epidemiology, UNC Chapel Hill
Co-PI, Carolina Center for Population Aging and Health
Dr. Aiello’s research seeks to integrate social and biological data across the life course, including epigenetic approaches, to identify the key triggers of population variation in susceptibility to dementia, poor mental health, cardiometabolic, and immune/infectious disease outcomes. Her overall research goal is to elucidate whether stress-related biological imprinting, through immune and epigenetic mechanisms, explain how health inequities from these conditions arise and produce disease risk across the life span.

Co-PI, Carolina Center for Population Aging and Health
My work focuses on how individuals and families respond to unexpected changes and how government programs and policies can help them adapt. Much of my research is about Indonesia before and after the 2004 Indian Ocean tsunami. I draw on household and community survey data that my colleagues and I have collected over the past 15 years, in combination with high resolution satellite imagery, to investigate how the disaster and subsequent recovery affect health and well-being at the population level.

Linda Adair, PhD
Professor, Nutrition

Linda Adair’s research focuses on maternal and child health and nutrition in low- and middle-income countries globally. She studies the determinants and long-term consequences of infant and early childhood feeding and growth patterns, the developmental origins of adult health and well being, determinants of healthy aging, and the role of HIV in maternal and child nutritional status, pregnancy and birth outcomes. She uses longitudinal analysis methods incorporating a life-course focus in numerous ongoing population-based cohort studies.

Christy Avery, PhD
Associate Professor, Epidemiology

Christy Avery’s research revolves around the promotion of cardiovascular health across the lifespan. To do so, Dr. Avery is interested in understanding the common genetic footprint shared by many chronic diseases as well as the influence of gene-environment interaction and genomic biomarkers, particularly metabolomics.

John Batsis

John Batsis, MD
Associate Professor, Division of Geriatric Medicine and Gillings School of Global Public Health

I have dedicated my professional career to caring for older adults through clinical care, research and education. Having the privilege of helping older adults maximize their physical function and quality of life through patient-centered, compassionate care motivates me in my work every day. My role as a clinician-researcher allows me to apply scientific principles of inquiry to enhance clinical care for an older adult population. Through learning and discovery of knowledge, we can maximize healthy aging by enhancing goal-directed care and healthcare delivery for older adults.

Kenneth A. Bollen, PhD
Henry Rudolph Immerwahr Distinguished Professor, Psychology & Neuroscience and Department of Sociology

Ken Bollen develops new quantitative methods to apply to the population and social/behavioral sciences. These include new models to analyze longitudinal data, creative approaches to analyze difficult to measure concepts, and developing estimators that have greater robustness to the approximate nature of our models. Population studies, health, and trauma are the contexts within which he develops these methods while also addressing practical substantive questions.

Yong Cai, PhD
Associate Professor Professor, Sociology, UNC Chapel Hill

Cai’s research focuses on China’s one-child policy and its implications for fertility and social policies. Specifically, his work shows that: China’s fertility has dropped to a level well-below the replacement; the demographic impact of the one-child policy was modest, much less than the government’s claim of 400 million averted births; socioeconomic development played critical role in driving China’s fertility decline; and the socioeconomic impacts of low fertility and population aging are substantial. The consensus on these issues, to which Cai contributed, provided the empirical and scientific foundation that persuaded Chinese government to end the three-decades long policy.

Her teaching integrates these research activities with interactive, learner-centered projects that promote critical thinking. Her leadership in service activities involves promoting the success of underrepresented groups in (bio)statistics and providing her professional expertise regionally and internationally.

Whitney Robinson, PhD
Associate Professor, Epidemiology, UNC Chapel Hill

Whitney R. Robinson is figuring out why Black women in the U.S. experience worse health and healthcare than other Americans when it comes to gynecological issues, cancer, and obesity. Her research focuses on everyday challenges (such as poverty during childhood, limited health care options, parts of the country where people live, and structural racism) and how they contribute to people’s risk of dealing with chronic health care issues. She believes that Black women are like “the canary in the coal mine”: the kind of changes that would improve the health of Black women would dramatically improve the health of all Americans.
