Our goal is to understand the neurobiological basis of disorders emerging in childhood and adolescence, including psychotic disorders. Our studies investigate these disorders longitudinally, within the context of brain maturation. We seek to understand the pattern and timing of changes as these disorders emerge and become established; and to identify neurobiological, neuropsychological and genetic markers of these illnesses. This will improve early (pre-illness) detection and diagnosis, and provide novel mechanisms for treatment.

Translating Membrane Proteins Into Therapeutics: From Bedside To Bench

This Program will build on previous pioneering work in order to address the following:

1. Improving understanding of how drugs interact with G-Protein Coupling Receptors (GPCRs) to achieve diverse pharmacology.

2. Improving understanding of the link between receptor and cellular behaviour, signaling and disease efficacy.

3. Increasing understanding of drivers of disease, to better treat specific symptom domains and increase understanding of the interplay of disease context on drug responses.

This Program of work will run for 5 years, with the MNC leading multiple projects relating to translational biology. Specifically, the Program aims to map brain-structure-function relationships and molecular signatures across developmental stages, the impact of insults at each of the stages, and the appropriate choice of pharmacological intervention to ameliorate their impact.
