Brief career history
Our research is focused primarily on understanding the roles of epigenetic mechanisms in the development and function of the zebrafish Central Nervous System (CNS), and how gene-environment interactions impact on these processes. In addition, we are exploiting the practical advantages of the zebrafish as a model organism to investigate the functions of genes implicated in human neurological disorders and cancer.
Integration of synaptic and neuroendocrine signalling and the role of the neural epigenome in health and disease
Epigenetic mechanisms regulate gene expression in response to a wide range of intercellular signals, conferring robustness to developmental processes and ensuring that there is a broad and reliable correspondence between genotype and phenotype. However, it is becoming apparent that epigenetic mechanisms also provide an experience-sensitive interface through which phenotypic plasticity is regulated in response to a wide range of environmental and behavioural signals across the lifecourse, and that these interactions can cause phenotypic changes that may be adaptive or maladaptive.
We aim to understand the roles of the epigenetic machinery, both in conferring developmental robustness and in mediating experience-sensitive phenotypic plasticity, within the zebrafish CNS. A particular focus is on understanding how experience-sensitive changes in synaptic activity and/or neuroendocrine signalling are integrated at the epigenomic level, and how the resulting changes in gene expression affect brain function.
We are collaborating with Dr Nils Krone to elucidate the impacts of altered steroid hormone signaling on zebrafish brain development and function, using novel mutants in which glucocorticoid synthesis and/or signalling is defective. We are also developing zebrafish models of nervous system disorders, such as epilepsy, by generating mutations in zebrafish orthologues of human epilepsy genes that are involved in synaptic vesicle formation and function. These models may be useful subjects of in vivo chemical screens to identify novel therapeutics for epilepsy and other disorders.
