I am an applied statistician and collaborate with research teams in psychology, epidemiology, and health services research. My work is methodologically versatile and includes large-scale cohort studies, cross-national surveys, small-n psychological experiments, and randomised controlled trials, as well as studies of health care records and birth registrations. Mental health and psychotherapy research are my particular focus. I have published two statistics textbooks and over 40 peer-reviewed academic journal articles. My Erdős number is 5.

Psychological treatments and psychotherapy research
I work with psychological therapists and academic psychologists to conduct randomized controlled trials of psychological therapies. These studies evaluate new interventions and estimate how effective they are. We also use mixed methods to investigate the therapy process and to find out why and how, not just if, therapies are successful.
I am a member of ChAPTRe, the Child Attachment and Psychological Therapies Research unit at the Anna Freud Centre and UCL.
Health Services Research
My collaborations with medical doctors and clinical academics involve observational studies of clinical records, administrative data, and purposely collected patient cohorts. These investigations evaluate care pathways and identify risk factors associated with poor outcomes for patients. I also work on innovative data visualization (control charts) that help hospital clinicians monitor patient outcomes in real time.
I am a member of HSRC, the Health Services Research Centre at the Royal College of Anaesthetists.
Social Epidemiology
With epidemiologists and other scientists I investigate health inequalities, as well as psycho-social and socio-structural causes of poor health, including mental health. These studies use data from national birth cohorts and large samples of clinical records.
I am an associate member of ICLS, the ESRC International Centre for Lifecourse Studies.
Methodology
I have published methodological work on social survey methods and on sequence analysis. I am interested in combining qualitative and quantitative data ("mixed methods"), particularly in the context of psychotherapy research.
I have taught statistics and research methods at university level since 2004. Within the Institute of Epidemiology and Healthcare, I co-lead the MSc modules Regression Modelling and Advanced Statistical Modelling. I have written two introductory statistics textbooks:
- P Martin (2021) Linear regression: an introduction to statistical models. London: Sage.
- P Martin (2021) Regression models for categorical and count data. London: Sage.
