“Our research focuses on understanding the causes of mental illnesses to improve their treatment. We primarily use functional imaging and experimental models in patients and controls”
Mental illness is a major cause of ill health and premature death. It accounts for four of the six leading causes of adult disability in the world and one in every ten hospital beds in the UK is allocated for the treatment of psychotic disorders such as schizophrenia.
Currently we are investigating brain changes that may lead to the development of psychotic disorders, using multi-modal imaging with PET and MRI. We are also examining the effects of cannabis and other drugs on the brain, and the influence of common genetic polymorphisms on brain function. We aim to understand why some patients respond to treatments and others don’t, using novel approaches to diagnose mental illness. We are also developing animal models for future drug development.
