(personal home page) Research ThemesInterestsMy interests lie in the mechanisms underlying neuronal and network function (and dysfunction), focusing on receptors and ion channels. Following my PhD in NMDA receptor function and regulation in midbrain dopaminergic neurons at Cambridge (under Dr. Sue Jones), I worked at Bristol (Prof. Julian Paton) and Bath (Prof. Alain Nogaret) developing low power solid-state neurons to be implemented as an artificial CPG in an EU-funded adaptive cardiorespiratory pacemaker. My current work, with Professor Allan Herbison, explores the mechanisms underlying episodic neuronal synchronisation within the kisspeptin neuronal network in the hypothalamic arcuate nucleus. I recently developed an acute slice preparation that exhibits spontaneous large synchronisations (similar to those observed in vivo) in this network for the first time, and we record from 100+ neurons bilaterally. We're currently investigating the mechanisms underlying this activity as well as the structure of the network. Research Focus
