Visiting professor in Mathematical Statistics

I am visiting professor in Mathematical Statistics at Linköping University at the Department of Mathematics, and professor in Statistics at the Swedish University of Agricultural Sciences at the Department of Energy and Technology.

Reserach profile

My research profile comprises linear models, multivariate analysis, bilinear models, high-dimensional analysis and matrix algebra. More than 100 peer reviewed articles have been written and 16 Ph.D. students have successfully defended their thesis. Three of these theses have been awarded the best thesis of the year in Mathematical Statistics/Statistics in Sweden. I have published one book entitled “Advanced Multivariate Statistics with Matrices” and a new book “Bilinear Regression Analysis, an Introduction” is to be published next year.

My work at Linköping University

I have mostly been working with Martin Singull but recently also started to work with Xiangfeng Yang. Over the years we have jointly organized three international meetings (funded by the Swedish Research Council and the Nordic Councils of Ministers) and jointly organized sessions within larger international conferences. Three Ph.D. students have defended their thesis and one more is on the way. Fifteen peer-reviewed articles have been produced together with Martin Singull and sometimes other coauthors. A number of successful applications have also been written.

Recent Developments in Multivariate and Random Matrix Analysis

The cover of
Festschrift in Honour of Dietrich von Rosen
Edited by Thomas Holgersson and Martin Singull

This volume is a tribute to Professor Dietrich von Rosen on the occasion of his 65th birthday. It contains a collection of twenty original papers. The contents of the papers evolve around multivariate analysis and random matrices with topics such as high-dimensional analysis, goodness-of-fit measures, variable selection and information criteria, inference of covariance structures, the Wishart distribution and growth curve models.
