My original interest in biology was how animals create their shapes in an amazingly robust and consistent manner. Since then I have been studying development of the vertebrate brain, contributing to understanding mechanisms underlying regionalization, neurogenesis, and histogenesis of the brain. Recently, our group became interested in some aspects of brain evolution, in particular its expansion in primates. We are particularly interested in the cerebrospinal fluid that fills up the lumen of brain ventricules in terms of its biochemical as well as physical role in brain development.
