Research Summary

Our laboratory is interested in mammalian development and disease and currently studies regulatory mechanisms at work in the skin, brain, and intestines.  We seek in particular to understand how morphogenetic regulators such as transcription factors or intercellular signals:  1) direct cells to develop or function as units, 2) promote tissue renewal or regeneration, 3) determine the polarity or size of developing tissues, or 4) target normal or malignant cells to specific anatomical locations.  Recently, we developed a method called “flash-forward genetics,” which provides a simple way to dissect the molecular basis of traits when the traits evolved in organisms difficult to study, such as mammals (see research article at https://doi.org/10.15252/embr.201949804 and accompanying commentary at https://doi.org/10.15252/embr.202052152).  Using this method, we sought and uncovered the first nude-like locus, a gene that functions like the mammalian nude locus and accordingly promotes the development of the hair and thymus.  In previous studies, we discovered a distinct class of skin cells, called pigment recipients, which control the behavior and size of the melanocyte population and thereby engineer their own pigmentation (see research article at https://doi.org/10.1016/j.cell.2007.07.024 and accompanying commentary at https://doi.org/10.1016/j.cell.2007.08.032).  Current projects in the laboratory include the analysis of murine models of vitiligo, Dandy-Walker syndrome, short bowel syndrome, and melanoma.
