My research areas span evolutionary biology, conservation genetics and ecological genomics. At present, I have focussed on investigating the processes responsible for local adaptation of plant species in the Darling range in Western Australia, with the applied goal of delineating seed provenance zones for post-mining habitat rehabilitation. This is particularly important in the southwest floristic region of Western Australia, which is not only a plant biodiversity hotspot but also is experiencing a boom in the resources sector. In the past, I have researched extensively in the field of plant-pollinator adaptation, in particular studying the processes responsible for the evolution and maintenance of pollination systems in the Orchidaceae whereby the plant deceives the pollinator into visiting without offering a nectar reward. I have considerable experience in the application of molecular genetics techniques in ecology and conservation biology, with students studying topics as diverse as quantifying the genetic diversity of rare species, determining the extent of clonal reproduction in plants, and estimating the extent of self-pollination. I also have applied genomic and transcriptomic approaches to ecology and conservation, with the aim of developing methods that more efficiently quantify adaptation and genetic diversity.
