Martin Schalling is Professor of Medical Genetics at the Department of Molecular Medicine and Surgery and the Center for Molecular Medicine at Karolinska Institutet and Karolinska University Hospital. Main interests include understanding mechanisms behind psychiatric and metabolic disorders thus enabling better diagnosis, prevention and more individualized treatment. He has supervised 20 PhD students and has authored 290 papers/manuscript and 120 abstracts to meetings and conferences. Several former students have reached the professor level. The research group has 30 members including affiliated clinical scientists. He currently supervises 9 PhD studens and 3 postdoctoral scientists. His papers have been cited over 17 000 times and his H index is currently 66 according to GoogleScholar. The KI External Research Evaluation (ERA) evaluated the group as Outstanding 2011.
Schalling is a visiting professor at University of Sao Paulo and has been a visiting professor at UCSD where he maintains research collaborations. He is the academic coordinator for KI collaborations with Mayo Clinic and University of Minnesota. Schalling is a member of the steering group at the Center for Molecular Medicine (CMM) as well as the Swedish Twin Registry. He is member of the editorial board of Open Psychiatry Journal, Current Psychiatry Reviews. He was member of the editorial board of Molecular Psychiatry 1995-2005, Genes, Brain and Behaviour 2001-2012. From 2003 to 2012 he was a member of the advisory board at Max Planck Institute. Schalling has been involved in organizing a number world congresses. In 2009 he was coChair of the World Congress of Psychiatric Genetics (WCPG).
Interactions with society include activites at several levels. Schalling is Chairman and board member of the Swedish Psychiatry Fund. He frequently lectures publicly and has written an number of debate articles on medical topics, most recently 2014 in Svenska Dagbladet Brännpunkt. He works actively with innovation processes with the aim of bringing scientific discoveries to the market and is in this context member of the board in small-medium sized enterprises (SMEs). He chairs a group within CMM that works towards facilitating innovation and more active translation activites.
He recived his MD degree at Karolinska Institutet in 1983 and in 1990 he got his PhD degree, also at Karolinska Institutet. Between 1990 and 1993, he was an EMBO postdoctoral fellow at Massachusetts Institute of Technology. Schalling became docent (associate professor) at KI in 1993. He was part of the two year program "future leaders of Karolinska Institutet" and has completed the one year MAL programme (Future Academic Leaders).
The aim of Martin Schallings’ research is to identify genetic, epigenetic and environmental factors that predispose to the development of neuropsychiatric and metabolic disorders such as depression, anorexia, schizophrenia, malnutrition in kidney disorder and obesity. His research group focus on genetic/epigenetic studies and functional studies in tissues and cell culture. KIgene, a core fascility for genetic and genomic analysis is housed within the group. KIgene supports research both within KI and outside and specialize in rapid and accurate turnaround, normally delivering data the day after recieving samples for analysis.
