My main interests focus on understanding how chemicals interact with the brain and contribute to the development of neurodevelopmental, neurological and psychiatric disorders.
My research questions begin with clinical observations or epidemiological evidence that chemical exposure is associated with an adverse health effect. We then investigate how that chemical can affect the brain leading to that particular health effect, providing a mechanistic link.
Low level pesticide exposure
There is epidemiological evidence that low level exposure to pesticides can lead to symptoms associated with psychiatric disorders. We investigated the effects of low levels of organophosphate pesticides on brain function using behavioural, neurochemical and electrophysiological technique to determine a mechanistic link.
We have recently expanded our work to investigate which pesticides people use in their homes to inform future studies on pesticide exposure and neurodevelopment in children.
Nerve agent exposure
We are currently optimising an assay to assess for nerve agent exposure.
Clinical observations indicate that the newer “legal highs” have mechanisms of action in addition to those that are known. We are investigating the effects of recreational drugs on brain function using neurotransmitter uptake and electrophysiological techniques.
We’re always keen to discuss our work with the public. One example is our recent partnership with a team of senior school pupils through the leading edge engagement programme. The pupils told me they were interested in examining the effects of chemicals found in soft drinks they consume. Under my supervision they developed and conducted their own experiment to test the ingredients. They found that some of the chemicals can affect motor activity. Their data and the partnership experience were published in a peer-reviewed scientific paper with the pupils as authors!
