My interests are broad: many questions about how the natural world works fascinate me, and I have published work for example on how sessile animal populations compete for space; how infauna are affected by predators; how animals can be aged; and escape responses to seastars. My most cited paper deals with how experimental treatments should be compared statistically. Current interests include how shell parasites interact with their hosts; how stress affects the immune status of abalone; what factors enhance collaborative management of fisheries; and how compensatory growth may affect fisheries managment models. Much of this work requires collaboration accross disciplines - integrated interdisciplinary research.
