Tim J Croudace BSc(Hon), Dip App Psych, MSc and PhD
Professor in Applied Health Research and Health Technology Assessment/HTA

I was appointed to a non-clinical chair at the School of Nursing and Health Sciences (SNHS) Jan 2015.

I am an expert in applied psychometrics and health research with extensive experience in epidemiology (social psychiatry and psychiatric epidemiology), behavioural research and cohorts studies, health services research and health technology assessment, as well as advanced quantitative methodologies. I have a career niche in Psychometric Epidemiology and enjoys research and training in Mplus, Stata and R.


I trained (B.Sc. Hons) as an experimental and applied psychologist (at the University of Nottingham) where he also completed his PhD and gained a Diploma in Applied Psychology (with Distinction). Soon after my PhD I moved into the medical school at Nottingham by joining the Department of Psychiatry. I remained in Nottingham obtaining collaborative grants in mental health services research and HTA. A Training Fellowship allowed me to gain further research methods training in latent variable modelling & multivariate statistics and a Masters degree (part-time) from the University of Sheffield (HSR&HTA).

Career history (after leaving Nottingham)

When the opportunity to work in Cambridge presented itself, I moved to the Department of Psychiatry in the University of Cambridge Medical School at Addenbrooke’s Hospital, with Prof Peter Jones (HoD), where I stayed for 10 years. During this time I won a Career Scientist Award from the Department of Health (duration 5 years) and grants from fu[1]nders including ESRC, MRC, The Wellcome Trust & NIHR. I was Director of Graduate Admissions for the Department of Psychiatry (PhD Programme) and a member of the Degree Committee. I became Honorary Research Director of The Psychometrics Centre.

I moved to York in 2010 to take up a Chair in Psychometric Epidemiology in the School of Health Sciences where his post was funded by the Hull York Medical School (HYMS). I became Director of Advanced Quantitative Methods for the White Rose ESRC Doctoral Training Centre, and lead for the Health pathway. I joined the NIHR TCC awards panel for post-doctoral awards and have served every year since, becoming Deputy Chair in 2015 and Chairing the Panel in 2017. Each year this panel makes awards for three NIHR competitions (Transitional Research Fellowships, Career Development Awards, and Senior Research Fellowshps). I am also a member of the ESRC Grant Peer Review College (PRC).

I have held Research Fellow, Lecturer and Senior Lecturer posts at Uni of Nottingham and Cambridge. I have held Personal Chairs at the University of York (Hull York Medical School) and University of Dundee.
