Eva’s research focuses on the biological (mainly genetic), environmental, and social determinants of health and their effects on cognitive function and dementia risk. Her work emphasizes the timing of these determinants and outcomes, ranging from examining exposures over the life course to longitudinal modeling of cognitive trajectories. Her research path started with studying the genetic basis of blindness using the fruit fly. Motivated by seeing the benefits of evidence-based decision making, she pursued a PhD in Population Health and a Master of Public Affairs. She acquired a set of multidisciplinary skills in epidemiology, genetics, demography, and policy analysis, which she now applies to studying health with a population perspective.
