Psychopharmacological and computational investigation of the cognitive mechanisms supporting paranoia.
My PhD project is “What is the relationship between dopamine modulation and social cognition and beliefs? Implications for the psychosis spectrum”.
I obtained my BSc (Hons) in Psychology and Neuroscience at the University of Leicester in 2011, and then followed on to complete my MSc in Clinical Mental Health at UCL.
The MRC DTP has given me the financial freedom and relevant supervision to train in pharmacological methods to address a meaningful research question, but also give me the freedom to explore my own ideas within a supportive team.
I’ve worked at Birkbeck (UK), Monash (Aus), and UCL (UK) as an RA on a number of interesting projects spanning neurofeedback, psychosis, social cognition, consciousness. All gave me vital research and career development skills, as well as being personally supportive. I’ve also worked as a mindfulness trainer, assistant psychologist, and mental health researcher at an app company – all have broadened my skills to help me think laterally and creatively in my current PhD.
