Profile Introduction

Genetics of mammalian eye development

Research Interests

Genetic basis of mammalian eye development and congenital eye malformations

We study genetic mechanisms of vertebrate eye development, evolutionary conservation of gene networks, and transcriptional regulation. Our major interests include early patterning of the optic primordia and retinal cell fate specification. We use mutant and transgenic mice, human pedigrees segregating congenital eye malformations, and a variety of genomic, molecular and cell-based techniques. Current lab projects focus on ganglion cells – the first-born retinal neurons whose axons form the optic nerves and relay all visual information from the eye to the brain, fate symmetry, bHLH transcription factors, Notch signaling, the retinoid pathway, and molecular identification of new eye disease loci. Among these, we are investigating how mutations restricting retinoid (vitamin A) transport across the placenta cause maternally inherited eye malformations.
