Dr Cathy Davies is a Postdoctoral Research Associate at the Centre for Neuroimaging Sciences, Institute of Psychiatry, Psychology & Neuroscience, King’s College London. She is currently working with Prof Steve Williams and Prof Sukhi Shergill to investigate the neural circuitry of cognitive dysfunction in psychosis and depression.


Cathy’s research interests centre on using MRI and experimental medicine to (a) better understand the neurobiological mechanisms driving the onset of psychosis, and (b) develop novel treatments that better target the underlying pathophysiology.


Previously, Cathy completed her PhD in Biological Psychiatry (2016-2019) within the Department of Psychosis Studies, supervised by Prof Paolo Fusar-Poli and Prof Philip McGuire and funded by the IoPPN Excellence PhD Studentship. Her doctoral research investigated treatments for people at clinical high risk of psychosis using network meta-analysis, MRI and pharmacological challenge with oxytocin. More recently, as a postdoc, Cathy worked with Prof Sagnik Bhattacharyya to examine the effects of cannabidiol on cerebral perfusion, neurochemistry and fMRI readouts in patients with psychosis risk.


Cathy has received a number of prizes and awards, including the King’s Prize for Outstanding Doctoral Thesis, PhD of the Year Award, Early Career Paper of the Year Award, SIRS Early Career Award and the BAP Hannah Steinberg and Robert Kerwin Prizes.
