About me

I am a statistical ecologist based in the Centre for Research into Ecological and Environmental Modelling (CREEM), where I am Director, and the School of Mathematics and Statistics, where I am a Reader. 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:

  • 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.
For more on these topics, see Links related to current projects.
