Bio 

After receiving my PhD in noradrenergic contributions to endogenous analgesia during neuropathic pain from the University of Bristol in 2014, I joined the Department of Surgery and Cancer at Imperial College London, where I completed 2 post doctoral positions. The first involved carrying out research into the structure and function of compressed spinal nerves in sciatica patients and the second explored the use of non-invasive brain stimulation in human surrogate pain models. I then moved to the Department of Neuroimaging at Kings College London to start a research fellowship using non-invasive deep brain stimulation in a human model of central sensitisation. 

In July 2020, I joined the University of Plymouth as a Lecturer in Human Neuroscience.

Teaching interests

I teach on the following undergraduate programmes:

PSYC302: The Psychology of Everyday Experience
PSYC418: Applying Psychology
PSYC603: Current Topics in Psychology 3
PSYC605: Research Project
PSYC756: Communicating psychological research

Research interests

My research is focused on understanding endogenous analgesic processes in human surrogate pain models and chronic pain patients. I use psychophysical approaches (e.g. quantitative sensory testing and conditioned pain modulation), electrocutaneous stimulation, neuroimaging and neuromodulation techniques (e.g. virtual reality, temporal interference) to investigate the sensitisation and modulation of central nociceptive activity. 

For more information see the Pain Neuroplasticity and Modulation Lab page at BRIC.
