My interest and expertise lies in quantitative agricultural and environmental science. The current areas of my work are:
- BVD, it's eradication and sample size calculation for screening for BVD
- The links between animal health and pollution
- Antimicrobial resistance and its measurement
- The consequence of empirically derived contact networks in cattle on the spread of disease
In addition to statistical modelling I have also published results from process-based modelling in BVD, Johnes and arable biodiversity.
My education is a degree in maths and plant science (Cambridge) and PhD in plant ecology (Liverpool) and statistical qualifications with the Open University and the Royal Statistical Society.
I have lectured on the Open University’s mathematical modelling summer school and I have run introductory courses to statistics for NHS Highland.
