Further Info


Professor in Psychiatry and Honorary Consultant Psychiatrist  with NHS Grampian, Professor David St Clair's career at the University of Aberdeen began in 1995 with a move from Edinburgh where he had held the position of Wellcome Trust Senior Research Fellow at MRC Human Genetics Unit.  Main research interest is understanding the basic causes of schizophrenia and developing new methods of diagnosing and classifying major mental illness.  He has made a significant contribution to the genetics of schizophrenia and is part of a both the International Schizophrenia and SGENE consortia who are performing genome wide studies of DNA from large numbers of schizophrenia cases and controls. Other ongoing studies in Aberdeen include schizophrenia bio-marker development and translational studies in Disc-1 transgenic mice.  He holds an advisory professorship at Shanghai Jiaotong University and an adjunct professorship at Columbia University.  He has identified pre-natal nutritional deficiency as a major environmental risk factor for schizophrenia and in collaboration with colleagues at Jiaotong and Shanghai large scale field studies have begun to identify the mechanisms responsible.
