Research Interests:
During embryonic development, a pool of rapidly dividing stem cells generates the complex architecture and function of the mammalian cerebral cortex. Understanding the molecular signals that control this process is a fundamental goal of developmental neurobiology. Our work is aimed at understanding how growth of the cerebral cortex is controlled in both wild-type mice and mutant mouse models of disease. We are particularly interested in the multiple progenitor cell types in the neocortical ventricular zone (VZ) and the factors that control their division and lineage progression during the course of development. We pursue these issues using a variety of cellular, molecular, and imaging techniques. In particular, we have a special focus on real-time analysis of molecules using in utero gene transfection and multiphoton imaging. The laboratory runs and maintains an LSM510 META NLO microscope from Carl Zeiss, Inc.
