Research Interests

Functional genomics of nervous system development.

My lab's main research interest is to understand molecular mechanisms of nervous system development in rodent model systems. We used DNA microarrays as a tool to identify genes that are developmentally regulated during mouse brain development. Candidate genes are characterized with molecular and cellular techniques and transgenic mice. In particular, my lab is interested in two areas: neural proliferation and synapse development. We have identified several candidate molecules that increase in gene expression during the period of neural proliferation or synapse formation and we are currently studying the role of two molecules (Mxd3 and SynDIG1) in these processes.
