I am broadly interested in ion channel neurobiology, and how ion channel activation, for example by the binding of a ligand, leads to opening of the ion channel and subsequent current flow.
Current projects are focused on determining the mechanism of activation of the AMPA-type glutamate receptor channels in association with accessory subunits known as TARPs. These receptors are found throughout the vertebrate nervous systems and underlie the majority of fast excitatory neurotransmission within the brain. Being so integral to brain function they underlie many of the molecular events involved in learning, memory, cognition, and motor control, and their dysfunction has been associated with many different neurological disorders.
The principle techniques utilized within the laboratory are electrophysiology, in particular single channel patch clamp, as well as molecular biology for the cloning and maintenance of DNA stocks. The single channel patch clamp technique allows the monitoring of currents from single ion channels in real time, and from this data kinetic information can be obtained that can be used to construct microscopic kinetic models. Robust kinetic models enable the quantitative determination of rate constant that define binding, gating, and other facets of ion channel receptor function, and can direct hypotheses regarding the effects of receptor channel modulation on neuronal function.
