Reasearcher Bio
Delusions are odd beliefs. They accompany many psychiatric illnesses, notably schizophrenia. A major challenge is to understand delusions in terms of changes in brain function. I attempted to meet this challenge by investigating the neural basis of human associative learning and belief formation, relating these processes to the formation of delusional beliefs. My findings have shaped the development of a novel mechanistic model of delusion formation.

In future work I will refine this model by applying human molecular genetic techniques and targeted pharmacological manipulations to delineate the contribution of specific neurotransmitters, as well as intracellular processes to the formation of delusions. In so doing, a fuller explanation of these puzzling symptoms in terms of genes, brain function and psychological processes will become tractable.
