Key innovations and the evolution of complex teeth in fish
By examining the evolution of complex teeth across ray-finned fishes, we show that it's the rate at which this innovation evolves - not the innovation itself - that accelerates species diversification. This work was recently published in Nature.
Are innovations subject to tradeoffs?
Using high-speed video and phylogenetic comparative methods, we're exploring the functional and evolutionary compatibility between two major feeding innovations in fishes.
What determines the effect of innovations on morphology?
Innovations can have varied effects on morphological evolution, but what determines these outcomes? We're exploring how complex teeth shaped diversification of the dental system in an adaptive radiation of African cichlids.
Biodiversity and aquaculture in Lake Victoria
Cage farming of Nile tilapia (Oreochromis niloticus) is a booming industry in Kenya. With the Kenya Marine and Fisheries Research Institute, we're monitoring how the expansion of aquaculture is impacting native fish communities, and the fishery as a whole, in Lake Victoria.
