Njål Foldnes

I hold a Ph.D. in combinatorial optimization from the University of Oslo, Centre of Mathematics for Applications. Currently I am working with problems in covariance structure analysis; structural equation modeling, and simulation of non-normal multivariate data.

I am also interested in education, and do research on the flipped classroom in higher education, as well as statistical analysis for the Norwegian Reading Centre.

ACADEMIC DEGREES
