I am currently a Professor of Educational Measurement in the Centre for Educational Measurement at University of Oslo. I joined UiO in September of 2015, where I enjoy conducting basic and applied research in international large-scale assessment. Prior to my appointment in Oslo, I was an Assistant Professor of Inquiry Methodology at Indiana University - Bloomington, where I taught courses in advanced quantitative methods. Prior to that, I was a research associate for the International Association for the Evaluation of Educational Achievment (IEA) - the folks that bring you TIMSS & PIRLS.

My experience with the IEA and my doctoral work at University of Illinois Urbana-Champaign has inspired my work in the field of international large-scale assessment (LSA). In particular, I am interested in critically analyzing the methods used to gather data and to produce achievement scores. I am also interested in methods and models for accommodating heterogeneous populations in latent variable models. I have a number of peer-reviewed and forthcoming papers in these areas. I regularly consult for international organizations including the IEA and the OECD and provide workshops on quantitative methods around the world. 

I have published an edited volume: Rutkowski, L. von Davier, M. & Rutkowski, D. (2014). Handbook of International Large-Scale Assessment. Boca Raton, FL: Chapman & Hall/CRC Press.
