Mental illnesses are a major cause of ill health and premature death. They account 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.

“Our research focuses on understanding the causes of mental illnesses and improving their treatment using PET and other functional imaging techniques" 

Current work in the group focuses on:

  • Understanding the brain changes that lead to the development of psychotic disorders, using multi-modal imaging with PET and MRI
  • Examining the effects of cannabis and other drugs on the brain, and the influence of common genetic polymorphisms on brain function
  • Determining why some patients respond to treatments and others don’t
  • Using novel approaches to diagnosing mental illnesses
  • Developing models for future drug development
