My main research interests are the history of taxation and inequality. I started working on late 20th century Spain, analysing the distributive impacts of the tax reform undertaken during the transition to democracy. I am now conducting comparative research on tax developments since the 19th century in Scandinavia, Western Europe and Latin America. I am also a member of the SWINNO project, where I look at the impact of public policies on innovative activities in Sweden and Finland since 1970.

I teach courses in Statistics and Data for Economic History and World Economic History. I have previously also taught on Introduction to History, History of the Welfare State, Economic History of Eastern Asia, Swedish Economic Development, and Economic History for the Swedish Labour Market. In my teaching, I strive for active student participation in analysis and discussion of various types of information (graphs, tables, texts, etc).

I am currently collaborating with the Inter-American Development Bank and the Brazilian tax administration in a project about tax evasion and inequality, which could have implications for other countries of the region.

I have made efforts at research dissemination for a wider audience during my career. For example, in the Spanish periodical Alternativas Económicas and the blog Nada es Gratis.and I have also cooperated for an article on income growth and inequality in Spain since the 1980s with El País (Más ricos y menos iguales, 25/10/2015). During some years, I wrote regularly in the blog "Universidad, Sí", which seeks to encourage public discussion of university issues.
