Biography
Biography
João Santos Silva graduated in Economics from the Technical University of Lisbon in 1985, and he received a masters degree in Applied Mathematics in 1988 from the same institution. In 1992, he completed his PhD in Economics at the University of Bristol. He taught at the Technical University of Lisbon and at the University of Essex, before joining the School of Economics in 2015. João's research focuses on theoretical and applied microeconometrics, and he has published in a variety of academic journals, including the Review of Economic Studies, Journal of the American Statistical Association, Review of Economics and Statistics, Journal of Econometrics, and the Journal of Business and Economics Statistics.
