What we study
The Fraser Lab investigates how vertebrate structures like teeth, skin appendages, and sensory organs evolve, develop, and regenerate, focusing on fish models such as sharks, pufferfish, and cichlids. They combine laboratory experiments, imaging (e.g., CT scans), and developmental analyses to uncover underlying genetic and patterning mechanisms.

Recent papers, explained
- The metamorphic transition of the frog mouth: from tadpole keratinized mouthparts to adult teeth
2025 · Royal Society Open Science
Compared frog teeth to other vertebrates, finding they form later and have unique mouth structures.
- Teeth outside the jaw: Evolution and development of the toothed head clasper in chimaeras
2025 · Proceedings of the National Academy of Sciences
