Alexis is an epidemiologist broadly focused on the causes and consequences of disparities in accelerated aging. She is particularly interested in the structural and psychobiological mechanisms that may produce early health declines in minoritized populations. Much of her work has focused on the health of women, especially Black women, as they enter into life-stages, such as the midlife menopausal transition where cardio-metabolic risk is high and disparities can exacerbate. Alexis also has expertise in causal inference, and applies causal inference theory and statistical methods to these areas of research to mitigate and quantify bias. Overall, her work aims to advance health equity and support minoritized populations to thrive as they age.
