My research is concerned with the systematics of caridean shrimps (Crustacea: Decapoda) in the broadest sense, ranging from alpha-level species taxonomy through to family level systematics, with forays into biogeography, faunistics, comparative morphology, ecology and conservation. Field work plays a prominent role, with recent expeditions in many locales in the Caribbean as well as the Indo-Pacific. As a result the OUMNH caridean collections are one of the largest in the world, offering significant scope for comparative morphology work, with SEM being the tool of choice.
