I joined the Institute of Psychiatry, Psychology and Neuroscience at King's College London as Professor of Medical Statistics and Trials Methodology in January 2018.


Prior to this, I held a personal Chair at The University of Manchester as Professor of Medical Statistics and was Deputy Director of the Manchester Clinical Trials Unit. 

Research Interests:

My research interests are in clinical trials methodology, and developing statistical methods for efficacy and mechanisms evaluation using causal inference approaches. The applications of these methods include randomised trials of complex interventions in mental health, and trial designs and associated analysis methods in precision medicine.


My research programme aims to answer four key questions about treatments when analysing clinical trials:


  1. Are treatments effective? 
  2. How do they work? 
  3. What factors make them work more effectively? 
  4. Which patients are they most effective for?


I develop clinical trial designs which aim to answer questions about treatments more quickly and using fewer patients.


For the Biostatistics Executive Education and PGCert in Applied Statistical Modelling and Health Informatics programme, I teach on the following courses:

  • Multilevel and Longitudinal Modelling (module lead) 
  • Structural Equation Modelling with Stata 
  • Causal Modelling and Evaluation 


For the MSc in Organisational Psychiatry and Psychology, I am the co-module lead for 'Organisational Research Methods'.


I teach lectures on clinical trials and intervention studies on the MSc in Global Health and the MSc in Psychiatric Research.


I contribute to the annual Epidemiology and Statistics for Mental Health Research course. 

Expertise and Public Engagement:

I am the lead for the joint department and Maudsley BRC Methodology Patient and Public Involvement group.


I sit on the NIHR Health Technology Assessment Researcher-led Committee.
