I am an elected member of the Council of the International Test Commission (ITC), an organisation committed to promoting effective testing and assessment policies and to the proper development, evaluation and uses of educational and psychological instruments. I also serve on the editorial board of the International Journal of Testing.
My previous experiences include teaching short courses in Applied Psychometrics at the University of Cambridge. Prior to that, I conducted research and test development at the Research division of SHL Group, where I had been Principal Research Statistician for many years.
