Research Interests

Alison has broad interests in statistical methods for ecological data. She has worked on a wide variety of data and research questions relating to biodiversity monitoring, climate change, impacts of wind farms on birds, species distribution modelling, protected areas, dynamic conservation, acoustic monitoring, illegal bird hunting, and farmland birds. She is passionate about using and developing statistical methods that help us understand ecological processes. Currently she is focused on analysis of data from the large-scale citizen science project eBird. Alison is interested in using statistics to account for biases, errors and challenges in citizen science data. Accounting for these challenges helps us to get the best information about the ecological patterns and process, which will help design and planning of efficient conservation measures. Alison has also worked to promote gender equality in science, through writing articles, speaking at events, organising events, and conducting scientific studies.
