I am Associate Professor (docent) in sociology and Senior Lecturer at the Department of Sociology at Umeå University. I am also an affiliated researcher at the Institute for Futures Studies, the Department of Sociology at Stockholm University, and the Department of Criminology and Social Work at Gävle University. With a background in engineering physics, I am interested in modelling social phenomena using large-scale datasets and non-traditional quantitative methods. My research is mainly concerned with social cohesion, how societies maintain it and how it is challenged. I address these questions through social network models of organizing processes, particularly applied to the dynamics of criminal organizing and collaboration. I also use life-course trajectory analysis to study migrant integration and neighbourhood segregation dynamics in Sweden.
