I am a Professor of Economics at the University of Oxford, a Senior Research Fellow of Lincoln College, and currently Head of the Economics Department. I have worked in Oxford since 1993, teaching microeconomics, labour economics, public economics and quantitative economics; from 2000 until 2016 I was the Tutorial Fellow in Economics at Lincoln College.  My research interests are mainly in labour economics, particularly equilibrium search and matching models, and their application to vocational training and other labour market policy questions. Other areas of interest are education, health and welfare policy.  I am involved in the CORE project, an international collaboration of university economists developing a new introductory economics curriculum for undergraduates.
