Our research program seeks to answer a variety of questions having both basic and translational relevance. Current efforts focus on:
• long-distance communication by specialized cellular projections
• intersections of hormonal controls with local mechanisms of differentiation and morphogenesis
• establishment and recruitment of post-embryonic stem cells during development and regeneration
• molecular and cellular bases for the evolutionary diversification of adult form
Much of our work uses zebrafish and related species, and emphasizes pigmentation, pigment cells, and their neural crest progenitors. Additional efforts focus on mechanisms of melanoma progression, development and regeneration of scales and skin in zebrafish, and appendage regeneration in salamanders.
Adult pigment cells in magritte mutant zebrafish
Past areas of research have included genetic controls of post-embryonic development and metamorphosis; behavioral significance of pigment pattern variation; molecular and endocrine factors in skeletogenesis and kidney function; zebrafish natural history in India; and pigment pattern development and evolution in amphibians. The lab has diverse interests and we are always happy to entertain new ideas. We welcome postdoctoral scholars, graduate students and undergraduates. For more information please see our website.
