Tarra has degrees in psychology and computer science from Dalhousie University and a PhD in epidemiology and public health from the University of Cambridge. Her research focuses on examining the impact of globalization on human and planetary health through studying the complex consequences of national policies implemented within political, social and commercial systems. Specifically, she is focused on generating population-level evidence for addressing the common drivers of the global syndemic of obesity, undernutrition and climate change. She uses systems thinking and draws on multiple methods from epidemiology, social and political science to evaluate national policy and explore opportunities within the commercial sector to transition toward healthy, sustainable and equitable food systems. Tarra is also interested in methodological aspects of evaluating the consequences of policy change, in particular, developing approaches to support understanding how and why policies work or fail in order to improve policy learning.
