After completing her MSc in technical chemistry and biochemistry at Chalmers Technical University, Sweden, I trained in clinical chemistry at the Sahlgrenska Academy, the University of Gothenburg in 1998. During my PhD, I switched fields from technical chemistry and biochemistry to human genetics and molecular and cellular biology. I completed my PhD at the Biomedicine Institute, Sahlgrenska Academy, the University of Gothenburg, Sweden, on a new disease entity 'Myosin myopathy', from 1999-2003. From 2008-2015 I was a Associate Professor in Experimental Pathology and an Swedish Research Council Fellow at the Biomedicine Institute and Principle Investigator of the Pathogenesis of new group of muscle diseases research group at the Sahlgrenska Academy, University of Gothenburg. I started at the University of Skovde in 2014 as a Senior Lecturer in Biomedicine and became a Professor in 2015. I am the head of the Neurogenetic disorder research group at the Translational medicine TRIM, School of Health and learning and Director of International Biomedicine Program at the University of Skovde.
I was awarded Queen Silvia's Jubilee Foundation Prize in 2004 for Research at Disabled children and young people. In 2013 my research proposal was elected in the European Research Council (ERC) Starting Grants and passed to the final step of the evaluation that was an interview by the ERC evaluation panel in Brussel. At the final panel my research proposal scored A, meaning Fully meets the ERC's excellence criterion. In 2015, I was elected of the Mobility Regional Excellence (MoRE) program, funded by the European Union's Seventh Framework Program for research, technological development and demonstration and Region Västra Götaland. The research project, ''Aetiology and pathobiology of inherited cardioskeletal muscle diseases'', was a collaboration with Professor Nigel Laing at the Harry Perkins Institute of Medical Research.
Since my thesis defense, I have developed and extended my research interests in several novel directions, established and developed new methods and new disease models to understand the pathogenic events that lead to muscle weakness in this group of diseases. These methods were useful in characterization of muscle pathology and pathophysiology of myosin myopathies. My further studies resulted to discovery of additional human muscle diseases with a comprehensive clinical, morphological, physiological and genetic characterization. I demonstrated and found that using simple organism such as the worms C. elegans would be an excellent disease model to study functional and structural consequences of myopathies. I am now interested in human tissue-culture cells and the fruit flies, Drosophila, as the disease models to study the functional and structural consequences of sarcomeric myopathies with main focus on muscle diseases and Protein aggregate myopathies.
