I have over 15 years of experience in wildlife abundance estimation, most of which were gained working with Steve Buckland and colleagues at the University of St Andrews, Scotland. I have an excellent understanding of survey design and data collection, with extensive field experience in the Southern Ocean, the Amazon Basin, and elsewhere. I started my consultancy in 2006, developing and applying cutting-edge statistical methods in the field of wildlife abundance estimation.

As a member of the Scientific Committee of the International Whaling Commission, much of my work is focussed on estimating abundance of whale and dolphin populations, primarily from line transect survey data, as well as data arising from dedicated observations from Platforms of Opportunity, such as fisheries survey vessels and ferries.

My main areas of interest and expertise are:

• spatial modelling (density surface modelling) of line transect data;
• survey design: aerial surveys and shipboard surveys;
• line transect analyses, including:
  - mark-recapture distance sampling (when detection probability on the trackline, g(0), cannot be assumed to be 1)
  - multiple covariate distance sampling (e.g. for incorporating different sightability conditions in estimating detection probability)
• river dolphin survey techniques.

I also have experience in spatial modelling of seabirds to assess the before-and-after impact of wind farm installations. Most of my experience is in applications in marine environments, but the techniques can generally also be applied to terrestrial situations.
