I am professor of mathematical statistics at Stockholm University. I am formally retired from October 2009, but re-employed part-time to give a couple of courses per year.
My interests are in statistical modelling and statistical methods, both theory and applications. Fields of active research or particular competence are: Inferential principles, Exponential families, Climate models and paleoclimate statistics, Biostatistics, Chemometrics (calibration and regression), Sampling survey inference, Stereology, Statistical consulting.
In the period 2007 to 2012 I have given two courses per year on Master/Ph.D. level: Statistical models, based on my own lecture notes on parametric statistical inference and exponential families, and Statistical Consulting, involving clients and projects from the departmental consulting service.
2012 and 2013 I have given part of the Linear models course.
Autumn 2004 I gave a course on Statistical theory for exponential families. Spring term 2005 I taught Linear statistical models and Statistical consulting methodology (this time in English), and led a course on Statistics for microarrays. Spring term 2006 I taught Linear statistical models and Principles of statistical inference (graduate level; based on a book manuscript by David Cox).
