I obtained my undergraduate degree in Psychology with Highest Honours from the University of Illinois, Urbana-Champaign. Prior to coming to Cambridge, I pursued my Master's degree in Human Development and Psychology at Harvard University.

Research Interests

I am currently a PhD candidate supervised by Professor Claire Hughes. The key question motivating my research is how culture and important social contexts (e.g., parents, peers and schools) interact to impact children's cognitive and social development. My PhD examines cross-cultural contrasts in the development of executive function (EF) in late childhood and explores the influences of proximal and distal family factors on children's EF and academic ability.
