Research Interests
The overall theme of our group is how neurons communicate with each other to achieve the desired neural function. Our work splits into two major areas: Neurophysiology and Technology development.
Neurophysiological studies
Our interests presently concentrate around the investigation of chemical signalling in the brain. One common theme is purinergic signalling by ATP and adenosine and its roles in several different functional contexts such as: centrally mediated chemosensitive reflexes involved in the control of breathing and arousal; signalling by hypothalamic tanycytes in the context of the control of body weight and food intake; homeostatic control of sleep; endogenous neuroprotective mechanisms in the brain; and during early development. We use a combination of electrophysiological, imaging and biosensing methods to study these problems.
Technology development
We have an active program to provide novel analytical tools for neuroscience research. In particular we are developing microelectrode biosensors specific for a number of transmitters to enable better exploration of chemical signalling in the nervous system. We have concentrated on microelectrode biosensors for the purines and have formed the Warwick Biosensors Group to further this aim. We are also developing biosensors for other analytes (such as glutamate, lactate, D-serine, acetylcholine) and have developed a range of highly selective biosensors for clinical diagnostic purposes. This latter work is linked to a spin out company Sarissa Biomedical Ltd specifically devoted to the commercialization of our biosensors and the development of diagnostic tools.
