Tom received an undergraduate masters (MSci) in ‘Neuroscience with study in industry’ from the University of Bristol, during which time he spent a year working at Eli Lilly on new drug targets for cognitive impairment in Alzheimer’s and Schizophrenia. He moved to Exeter as a PhD student under the supervision of Dr Jon Brown and Prof Andrew Randall after which he took up a role as a postdoctoral researcher in the Exeter applied Neurophysiology group investigating entorhinal cortex dysfunction in rodent models of dementia. In 2020 he was appointed associate lecturer in Neuroscience.

Tom is interested in how neurological diseases such as Alzheimer’s disease and frontotemporal dementia produce changes to neuronal networks that ultimately affect cognitive processes. He uses in vivo electrophysiological recordings to measure the activity of neurons from awake-behaving mice, either at the level of single-cells or through large-scale neuronal networks. His work has focused on the medial entorhinal cortex, one of the first areas to be affected by Alzheimer’s disease pathology, which is which is essential for processing spatial information.

Tom primarily teaches on the BSc Neuroscience course. He has experience teaching on a wide array of modules across all academic years, using a variety of delivery methods:

  • Final Year Academic lead for BSc Neuroscience
  • Module lead: NEU2001: Advanced methods in Neuroscience (30-credit module focussing on Neuroscience methods) and NEU2002: Brain and Behaviour (15-credit module focussing on bridging the gap between synaptic physiology and animal behaviour).
  • Lecturer: Gives lectures across all years of the Neuroscience BSc course, focussing primarily on Neuropharmacology (NEU1006, NEU2019), Brain networks and Behaviour (NEU2002, NEU2018) and Neuroimaging and therapeutics (NEU3030)
  • Final year project supervisor: Runs several final year research projects each year, as well as supervising critical reviews on a variety of Neuroscience topics (NEU3001). 
  • Small group facilitator:  Runs small groups in Advanced methods in Neuroscience (NEU2001) and journal club/tutorial sessions in Frontiers in Neuroscience (NEU3008). Also runs special study unit (SSU) for first year BMBS (3-week unit on ‘The Inner GPS of the Brain: How Cognitive Maps Influence Health and Disease’).
