My research interests lie mainly in industrial organisation, covering both theory and applications to public policy. A particular focus is digital media industries: in 2007 I completed an ESRC-funded project on "The Economics of Broadcasting in the Digital Age” and in 2009 I completed a Microsoft-funded project on “The Impact of Technology on Market Structure in Media Industries”. I have published journal articles in the Review of Economic Studies, Economic Journal, European Economic Review and International Journal of Industrial Organization, among others. I have also written a number of policy papers and frequently comment on policy issues.

My research papers have attracted over 1,000 citations at Google Scholar.
