I am a Professor of Biostatistics working in the Biostatistics Research Group in the Department of Health Sciences at the University of Leicester, UK. I also work part-time in the Biostatistics Group in the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden.
I have a variety of interests, mainly in the area of survival analysis in epidemiology. Much of my work focuses on the analysis from data from national cancer registries. I particularly enjoy writing software to enable transferal of new methods into practice.
I enjoy teaching and have developed some interactive graphs to help with communication. Related to this we have developed interactive graphs to display various cancer survival measures, called InterPret.
PhD in Biostatistics, 1999
University of Leicester, UK
MSc in Medical Statistics, 1992
University of Leicester, UK
A full list of my publications can be found here
I have written a book with Patrick Royston titled Flexible parametric survival models using Stata: Beyond the Cox model.
A review of the book can be found here
In the software section of my webpage you will find some tutorials on using these models.

I have developed a number of Stata commands. I have added some examples of using this code and intend to add to these over time.
I have worked with Paul Dickman, who has written some excellent Stata tutorials, many of which use my commands.
My main teaching is on the MSc Medical Statisics at the University of Leicester. I was a student on this course way back in $1991 / 1992$.
In $2019 / 2020$ I taught on the following teaching weeks for the MSc and expect to do the same in $2020 / 2021$,
Below are some upcoming course.
23-25 January 2021 Parametric Competing Risks and Multistate models, Swiss Epidemiology Winter School, Wengen, Switzerland (CANCELLED).
1-6 June 2020. Paul Dickman and I will teach a 5-day course on statistical methods for population-based cancer survival analysis in Veneto Italy. Further details available here. (CANCELLED)
