I study the evolutionary ecology, behaviour
and phylogeography of marine animals. Laboratory clones
of the sessile marine invertebrate Celleporella
hyalina serve to investigate a wide range of evolutionary
problems, including mechanisms for ensuring cross fertilization
(PNAS 2002), adjustment of sex ratio in response to stress
(PNAS 2003), histocompatibility in relation to coancestry
(Evol. Devel. 2004) and plasticity of body size in relation
to temperature (Evol. Devel. 2006). In collaboration with
we have used DNA barcoding in conjunction with breeding
tests to reveal prolific cryptic speciation in C.
hyalina, having important implications for estimating
marine biodiversity and predicting biogeographical impacts
of climate change. Current NERC-funded research uses C.
hyalina as a model system for testing theoretical
predictions of the effect of self-fertilization on the sex
ratio of simultaneous hermaphrodites. For more information,
