Nina is a doctoral student in the Economics of Education and Educational Policy programs at Stanford University. She holds a Master's degree in Economics (MA) from the Federal University of Minas Gerais (UFMG - Brazil), and a Bachelor's degree (BA) from the São Paulo School of Economics (EESP). Most recently, she worked as a consultant at the World Bank, in Latin America and the Caribbean region, and at Mgov, a mobile platform for policy design and impact evaluation. Nina studies the economics of education, with a particular interest in teacher quality and parental engagement. She is strongly interested in quantitative methods and causal inference and she is currently involved in three randomized trials studies. The first investigates whether enhancing communication between schools and parents improves students performance and what mechanisms drive these effects. The second seeks to shed light on how poverty may impose a psychological tax on parenting, possibly generating a poverty trap. The third explores whether improvements in teacher practice can be stimulated by providing schools with performance feedback based on classroom observations, practical suggestions and coaching support for more effective pedagogy.
