Current and Previous Academic Affiliations

As of 04/2010 I am Marie Curie Postdoctoral Fellow on a 3-year independent International Outgoing Fellowship (IOF), awarded by the EU Commission under the FP7-People Marie Curie Actions Program, at the Department of Economics, Northwestern University (as "outgoing host" in the first two years), and the Department of Economics, Aarhus School of Business, Aarhus University (as "EU host" in the third year).

I am also associated with the Labour Market Dynamics and Growth (LMDG) research group (head: Dale Mortensen), of the School of Economics and Management, Faculty of Social Sciences, Aarhus University (since the end of 2007), and with the Center for Corporate Performance at Aarhus School of Business, Aarhus University (since 10/2005).

From 04/2008 to 04/2010 I was Postdoctoral Fellow on a two-year independent grant awarded by the Danish Council for Independent Research--Social Sciences ("FSE"), at the Department of Economics, Aarhus School of Business, Aarhus University and the Center for Corporate Performance. Before that, as of 10/2005, I was Research Assistant at the same place, on a research project lead by Niels Westergaard-Nielsen.

I was Visiting Researcher at the Department of Economics, Free University Amsterdam (VU) (invitation by Gerard van den Berg) in Spring 2009.

Between 09/2002 - 11/2008 I was PhD candidate (Promovendus) at the Department of Economics, Erasmus School of Economics, Erasmus University Rotterdam  and the Tinbergen Institute (until 09/2005 I was employed as Research Assistant at the same Department of Economics, Erasmus School of Economics, Erasmus University Rotterdam). My supervisor was Coen Teulings. The public defence of my thesis took place on the 27th of November 2008, at Erasmus University Rotterdam (inner commitee: Gerard van den Berg, Maarten Janssen, Jean Marc Robin and Coen Teulings; further members in the plenary commitee: Robert Dur and Otto Swank).

In Spring 2005 I was Visiting Scholar at the Department of Economics, University College London. My advisor there was Richard Blundell.
