Professor in Statistics at Umeå University
Membership period 2013-2018
I develop statistical methods in order to evaluate and analyze standardized achievement tests and large scale assessments. These tests include admission tests and licensure tests. An overall focus has been on developing methods in order to ascertain high quality over time in standardized achievement tests. This is especially important when a test is valid during several years and is given repeatedly to test takers, as e.g. admission tests. A large part of my research has focused on the development of methods for equating test scores, i.e. the statistical process which is used to ascertain that test scores from different test forms are comparable. Especially, I have had an active part in developing local equating, i.e. the idea of using an equating family instead of a single equating transformation.

“I a member of the Young Academy of Sweden in order to influence research policy and to take part in forming the future's research system. The vision is that the future system promotes the best research, has clear career paths while being equal, fair and transparent. As a statistician, I have worked interdisciplinarily continuously, and it is a great advantage and incredibly evolving having so many disciplines represented in the Young Academy of Sweden.”
