Research Interests

I study the relationship between evolution, development and regeneration in a range of vertebrate structures, including teeth, skin appendages and sensory structures. The work in the Fraser Lab is centered on the study of a selection of intriguing fish models of evolutionary developmental biology (EvoDevo), including pufferfish, cichlids and sharks. Some of our most recent projects have focused on tooth regeneration and we have discovered stem cell niches associated with the continuously regenerative dentition of sharks, and the tooth-to-beak transition that occurs during pufferfish development. Our lab is interested in how vertebrates make, shape and regenerate complex morphologies. We have also recently discovered that shark skin teeth (denticles) develop via a highly conserved Turing-like patterning mechanism; a developmental process shared with bird feather and mammalian hair development.
