I am a statistician. A biostatistician as it happens. A medical statistician really. Or should it be data scientist? Am I in data analytics? I’m a biostatdatscientanalyst.

Now that’s cleared up I can tell you what I’m interested in: data. And people*.  And science.

Our progression as a species can be primarily attributed to our aptitude for handling information, from the pattern recognition that helped us spot predators in prehistory to our capacity for abstract thought that allowed us to identify solutions to our most difficult problems (someday we may even figure out how Mark Wahlberg is our species highest paid actor). All this requires an ability to process and make sense of data. This is the work of a biostatdatscientanalyst.

I am specifically interested in physical activity. Physical activity is fascinating. Everyone knows it’s good for you right? But how good? And for what? And how do you measure it anyway? All of this interests me. I come from a clinical trials background and many of the trials I work(ed) on (have) include(d) elements of physical activity for health, be that functional ability, weight loss or mental health. I am particularly interested in the analysis of accelerometry data.

I am also interested in mental health. Mental health measurement and intervention is another difficult problem and so is grist to the mill of a biostatdatscientanalyst. I have milled the grist out of: common mental disorders, bipolar disorder, suicide and post-traumatic stress disorder.

Methodologically I am interested in multilevel modelling, meta-analysis and R programming.


I contribute to teaching two undergraduate courses: “Probability, Statistics and Data”, and “Statistical modelling and Inference”. I also run meta-analysis training with Cardiff University and University of Exeter, contribute to a MOOC called “Making Sense of health Evidence: the informed Consumer” and teach an introduction to R course in the University of Namibia as part of Cardiff University’s Phoenix project.


Other bits

I am a research Fellow with the Turing Institute.

I am an editor for Statistical Methods in Medical Research and statistical editor for the International Journal of Behavioral Nutrition and Physical Activity

I am on the middle career researcher section of the Society for Social Medicine.

I organize the Statistical Science seminar series for the statistical science group at University of Exeter.

I am available to supervise undergraduate projects on physical activity or mental health.

I blog infrequently at SignificantlyStatistical

I sit on a number of committees for trials including:

Chair of the 'Helpmedoit!' a web and text based intervention to facilitate social support to achieve and maintain health-related change in physical activity and dietary behaviour
