My research is focused on understanding how animals move, and how these underlying movement processes affect inferences obtained from detection data. Specifically, my PhD work involves developing mechanistic movement simulations based on spatial memory and individual interactions, and using them to i) evaluate statistical models of population abundance estimation and ii) evaluate animal population control measures to assist in management decisions.
My longer-term interests are in novel statistical approaches that improve the strength of community inferences from camera trap data. I endeavour to apply these methods on local-scale carbon-biodiversity research to support the integration of biodiversity effects in carbon offset schemes.
