Pain is one of the largest and costliest medical problems in the developed world and it is likely to get worse1,2. There is no cure for pain and the current treatments are poorly suited as long-term solutions3,4. Developing sensible strategies to this complex clinical problem depends on our understanding of the fundamental biology of pain.
At the most basic level, it is well known that the magnitude of pain experienced by an individual is not necessarily related to the nociceptive input to the body 5,6. In part, this is because pain is a complex subjective experience that is contingent upon numerous factors. Implementation of brain neuroimaging methods has greatly facilitated our understanding of the key role that the central nervous system (CNS) plays in these processes 7-18.
What is lacking is a mechanistic understanding of how the perception of pain emerges from nociceptive afferent input to the brain; and further, how these processes can become dysfunctional in chronic pain patients.
My research targets this need by interrogating pain-related neural activity across multiple spatial and temporal scales in the brain, brainstem and spinal cord using advanced neuroimaging and analysis techniques.
Deliverables from my work include both forward and reverse translation studies into relevant animal models of nociception and chronic pain patients – projects which I am pursuing in collaboration with both clinical and basic science researchers in the UK and USA.
My work has been published in top neuroscience, neuroimaging and clinical research journals (e.g. Nature Neuroscience, Brain, Neuroimage, and Pain), and was recently featured as part of a documentary on BBC Radio 4 (see: http://www.bbc.co.uk/programmes/w3cswdkg).
