Ann Marie Janson Lang (earlier Ann Marie Janson, married in 2004) obtained her MD at the Karolinska Institutet, Sweden in 1983. Her research interest arouse in the early 80s when she worked with Professor Johannes Rhodin at the University of South Florida, Tampa, FL, USA. In the mid-80s she joined the laboratory of Professor Kjell Fuxe and received a PhD degree in 1991 at the Karolinska Institutet. The title of her thesis was: 'Protective actions of nicotine on lesioned nigrostriatal dopamine systems'. After seeing her first parkinsonian patients and receiving a certified license to practice as a physician by the Swedish National Board of Health and Welfare in 1993, she made the decision to focus on finding new strategies to treat Parkinson's disease and went back to full-time research. She started her own research group on experimental parkinsonism and held a faculty position sponsored by the Swedish Research Council at the Department of Neuroscience at the Karolinska Institutet. In 2004 she received a position as Associate Professor at the Department of Medical Nutrition of the Karolinska Institutet. Dr. Janson Lang leads a research team working on injury and repair of the nervous system. Her expertise in Quantitative Neuroscience (co-editor of a book with the same title, Oxford University Press ISBN 0198505280), has allowed her to study issues related to nerve cell death, neurogenesis and neuronal turnover in the adult brain. Janson Lang is inventor of two patents in this field. She has more than fifty publications on neurodegeneration and neuroprotection, with a focus on techniques to protect, rescue or repair the partially injured nigrostriatal dopamine system. Janson Lang serves in the board of the Swedish Movement Disorder Society (Swemodis, Swedish associate of the international Movement Disorder Society) and has received awards in teaching (Karolinska Institutet, 1997) and research (Swedish Medical Society, 2003).
