Research interests

All my research has been devoted to Graphical Markov Models. The class of Graphical Markov Models is so vast that includes many existing models, like Structural Equation Models, log-linear models, and so on, that I never get tired in exploring them from the theoretical point of view and in using them in applied data analysis.


From the theoretical point of view I have been attracted by issues of identification and distortion induced by unobserved factors. For that I have also received a grant from the American Institute of Mathematics AIM ('SQuaRE' grant: 2011-2013).  Papers that address the identification issues are e.g. 6, 7, 9, 10, 14, 24 of the paper list below. Papers that address issue of distortion are e.g. 1, 2, 5, 11, 17. In many applied research I have been using Graphical Models with latent variables: see papers 5, 6, 16, 23 or the book chapter 2 on capture-recapture estimation.


Currently, I am a member of SIMSAM,   Interdisciplinary research group on early life exposure and health: A registry-based life-course  perspective with modern epidemiological and statistical approches, at Umeå University.


Further Research Interests include Credit Scoring see e.g. paper 8 or 13, and book 5.
