I am a statistical ecologist based in the
Centre for Research into Ecological and Environmental Modelling (CREEM)
at the University of St Andrews. CREEM is nominally divided up into
research units, and some of my work is within the
Research Unit for Wildlife Population Assessment (RUWPA).
I am also part of the National Centre for Statistical Ecology (NCSE) and
Scottish Oceans Institute (SOI).
There are two main strands to my work:
For more on these topics, see Links related to current projects.
- Use of computer intensive methods to fit and compare stochastic models
of wildlife population dynamics. I mostly work on algorithms called particle filters.
Here is an accessible article about some of this work.
- Development of methods and software for estimating the size, density and distribution
of wild animal and plant populations. I mostly work on a group of related methods
called distance sampling.
Here is a poster giving an accessible overview of some of this work.
Here is an introductory article on distance sampling.
- MT3607: Computing in Statistics. Co-taught with Eric Rexstad. Class will next be taught in Semester 1 (i.e. Sept-Dec) 2014.
- International training workshops in distance sampling and wildlife abundance estimation.
