The over-arching theme of my research is to understand the origins and determinants of non-marine biodiversity, both native and alien, primarily in the Pacific. Systematics provides the essential framework and conservation underlies all aspects of the research, which integrates a range of subdisciplines and approaches, including taxonomy, phylogenetics, genetic diversity, biogeography, invasion biology, and ecology. DNA sequencing and cladistic analyses are important techniques in much of this research. The four main focuses are:
Current projects: Nomenclature, systematics, phylogenetics, biogoegraphy, and origins of land snails throughout the Pacific. Evolution of shell size and shape in Pacific island land snail faunas. Systematics, phylogenetics, and biogeography of apple snails globally.
Current projects: Ampullariid snails as model invaders. Molecular and morphological diversity of invasive subulinid land snails and veronicellid slugs in Hawaii. Distribution and impacts of alien snails in Hawaii.
Current project: Geographic distribution of rat lungworm and its prevalence in native and alien snail/slug vectors in Hawaii.
