Research Interests

I am interested in the evolution of development. Several different animals are used in my research. The teleost Astyanax mexicanus is a single species with eyed surface dwelling and blind cave dwelling forms. I want to understand the developmental and evolutionary mechanisms responsible for phenotypic changes in Astyanax cavefish. I am also interested in the ancestry of the neural crest and regeneration in chordates. For this research I use sea squirts (ascidians), especially Ciona intestinalis, which has a completely sequenced genome.
