Katrina L Kezios, PhD
Assistant Professor, Epidemiology - Boston University School of Public Health
Biography
Katrina Kezios is a life course epidemiologist and Assistant Professor in the Department of Epidemiology at the Boston University School of Public Health. She received her MPH and PhD in Epidemiology from Columbia University, where she completed an interdisciplinary NIEHS T32 predoctoral fellowship in Environmental Life Course Epidemiology.
Dr. Kezios’s research centers on the life course biosocial determinants of aging-related processes and outcomes, and she has worked on studies that collectively span the life course—from birth cohorts to aging cohorts. A primary focus of her applied work is understanding how chronic exposure to social and financial stressors harms cognition and impacts dementia risk. In much of this work, she employs novel methods to overcome challenges in life course research, leveraging her expertise in life course theory and methods, epidemiologic methods, and causal inference. She is currently the PI of an NIA funded study that uses data fusion methods to construct a longitudinal synthetic cohort to examine how life course financial wellbeing shapes cognitive aging.
Dr. Kezios also leads meta-research studies evaluating how core concepts and principles in epidemiologic training are reflected in research practice, a research area influenced by her experience teaching epidemiologic methods.
