Given the difficulty of directly debiasing cognitive and social biases, Ariella's research focuses on how environments can be structured to reduce biased behaviors and outcomes. Ariella is currently pursuing two main strands of research: the first is a focus on understanding how people's beliefs related to various self-control strategies affect goal achievement, and the second is a focus on increasing diversity and inclusion in the workplace.
Ariella is a doctoral student in Organizational Behavior at Harvard Business School where she studies behavioral design. Specifically, she is interested in how environments can be structured to reduce bias in the workplace, in educational settings, in the online context, and in the domain of self-control. She is also a Lara Warner Scholar of the Women and Public Policy Program at Harvard Kennedy School.
Previously, Ariella worked for the Behavioural Insights Team in London, where she applied findings from behavioral science to public policy. She has focused on delivering policy advice and designing and implementing field experiments related to sustainable transportation, criminal justice, and organizational behavior. Ariella graduated from Yale University with a BA in Ethics, Politics, and Economics.
