The cross-cutting Biostatistics, Epidemiology, Mathematics and Ecology group is led by Professor William Browne. The group covers a wide selection of research interests, all with a quantitative theme and ranging from statistical methodology and software development work, through statistical modelling, to more applied epidemiology work both in the UK and overseas. The group also works on mathematical image analysis techniques and modelling of disease.

In Biostatistics, the group specialises in the application of and software development in multilevel random effect modelling; several group members are also members of the cross-faculty Centre for Multilevel Modelling.

In Epidemiology, the group has strengths in modelling diseases and welfare in most species including both farm and companion animal both in the UK and in an international context. There are specific interests in mastitis and bTB in cattle, fin erosion in fish, feather pecking in chickens and obesity in cats.

In Mathematics, the group has strengths in image analysis within the immunology group and modelling of infectious diseases in both animals and humans. The group also work work on Ecology problems and collaborate with researchers in the biology department.

The group collaborates extensively with other academics within the three main research groups, the wider University and further afield. Members of the group have led or been involved in work funded by the BBSRC, ESRC, EPSRC, NERC, Defra, Wellcome, FAO, FSA, EFSA, RSPCA, Cats Protection and John Oldacre Foundation, to name a few.
