Research Abstract

Our lab is interested in fundamental mechanisms governing development of the cerebral cortex. We are interested in genes that control neuronal proliferation and cell fate selection, and are using positional cloning to identify genes that when mutated cause the human cerebral cortex to be too large or too small. Abnormalities of some of these genes are likely to be quite relevant to human neural tumors. We are also interested in genes that regulate neuronal migration, which provides a genetic system for analyzing cell migration in general.
