Kajsa Yang Hansen

Guest Professor

Staff member at Division of Educational Science and Languages.

Conducts research in social sciences.


Her research focuses on issues concerning educational quality and equity in Sweden and across different education systems. She has led and conducted several research projects financed by the Swedish Research Council (VR) to explore these issues. Currently her research covers investigating consequences of school reforms to educational equity in Swedish schools; the compensatory effect of different school systems on educational equity; trend in opportunity to learning. 


Kajsa’s methodological interest lies in the quantitative analytical methods such as Structural Equation Modeling, multilevel analysis, growth curve modeling and mixture modeling.


Kajsa teaches postgraduate courses on the above-mentioned methods, and supervises Master and PhD students with their substantive research questions. 


She is a member of the stirring group of the VR financed Quantitative Research Methods School (QRM), started in 2018, with the focus on delivering and promoting advanced quantitative research methods to doctoral students and post-docs in social behavioral sciences. She also involves in an EU training project ETN OCCAM (European Training Network: Outcomes and Causal Inference in International Comparative Assessments).
