    About me

    I’m a lecturer in mathematics and statistics, mainly teaching statistics units. I have taught a biostatistics unit, an applied statistics unit, a statistical design and data analysis unit, a probability and statistical inference unit, an introductory statistics unit and a fundamental mathematics unit. My research is focussed on saddlepoint approximation methods, genome-wide association studies, statistical applications in veterinary studies  and statistical methodology in quarantine (border security) inspection methods.
