Our group is interested in the neurophysiological changes associated with neurological diseases, in particular Alzheimer’s disease and schizophrenia. Experimentally the major part of our work involves a host of electrophysiological methods stretching from single channel recording, through cellular neurophysiology in vitro, to tetrode recordings of neuronal activity in vivo. We also utilise a number of optical methods including single cell imaging and photo-activated ion channels such as Channelrhodopsins.

We work in close association with the pharmaceutical industry who fund much of the work in the lab. We also have a host of collaborations within Bristol the research community.
