Mark Emerson is a developmental neurobiologist interested in understanding the molecular and cellular mechanisms underlying neuronal specification, with an emphasis on cone photoreceptors of the vertebrate retina.  We use electroporation technology, imaging, biochemistry, and RNA-Seq transcriptome analysis to explore the direct connections between cis-regulatory elements, protein complexes, and ultimately cellular identity.
