Our research interests focus on the development of novel treatments for severe psychiatric disorders, especially schizophrenia, through an application of multimodal neuroimaging, genetics and enviromics to characterize brain circuits underlying the risk for mental illness and cognitive dysfunction.
Many severe psychiatric disorders and complex behaviours are highly heritable. We investigate genetic variation associated with risk for disorders such as schizophrenia, depression and autism and behavioural phenomena such as attachment or impulsive violence in a translational approach, with an emphasis on multimodal neuroimaging to identify neural systems mediating genetic risk. The ultimate goal is the construction of a neural risk architecture of the studied target behaviour as guide for the discovery and evaluation of novel treatment strategies.
We are focusing on these major aspects
- Neurogenetic risk mechanisms of depression and anxiety
We study the impact on genetic risk on neural function and cognition using multimodal neuroimaging. A recent focus of that work is the investigation of epistatic interactions, relating multiple genetic variants to neural phenotypes, and the study of neural mechanisms predictive of therapeutic response and course in a longitudinal perspective.
- Neural mechanisms of complex social behaviours under genetic control
Many aspects of social behaviour are highly heritable, are key components of severe psychiatric disorders that are themselves heritable, and are essential for reproductive fitness. Consequently, we have launched a program to investigate genetic contributions to the human social brain.
- Genetic modulation of neural plasticity
The goal of this project is to identify the functional correlates, neurochemical mechanisms and the impact of genomic variation on experimentally induced prefrontal cortical plasticity in the human.
