    Current Research and Scholarly Interests Our lab studies how intricate control of gene expression and cell signaling is regulated on a minute-by-minute basis to give rise to the remarkable diversity of cell types and tissue morphology that form the living blueprints of developing organisms. This research aims to add a new dimension to our understanding of how cells ?know? where to go, when to move and differentiate by employing novel technologies that probe these questions at a highly molecular and nanoscale level. Work in the Barna lab is presently split into two main research efforts. The first is investigating ?specialized ribosomes? and mRNA translation in control of gene expression genome-wide in space and time during development. This research is opening a new field of study in which fundamental aspects of gene regulation are controlled by ribosomes harboring a unique activity that ?select? for specific mRNAs to translate by virtue of unique RNA regulons embedded within 5?UTRs. The second research effort is centered on employing state-of-the-art live cell imaging to visualize cell signaling and cellular control of organogenesis. This research has led to the realization of a novel means of cell-cell communication dependent on a dense network of actin-based cellular extension within developing organs that interconnect and facilitate the precise transmission of molecular information between cells.

    Ben Barres

    Professor of Neurobiology, of Developmental Biology, of Neurology and, by courtesy, of Ophthalmology

    Current Research and Scholarly Interests Our lab is interested in the neuronal-glial interactions that underlie the development and function of the mammlian central nervous system.

  • Philip Beachy

    Philip Beachy

    The Ernest and Amelia Gallo Professor in the School of Medicine and Professor of Developmental Biology

    Current Research and Scholarly Interests Function of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation), in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.

  • Gill Bejerano

    Gill Bejerano

    Associate Professor of Developmental Biology, of Computer Science and of Pediatrics (Genetics)

    Current Research and Scholarly Interests Dr. Bejerano, co-discoverer of ultraconserved elements, studies the Human Genome. His research focuses on genome sequence and function in both humans and related primate, mammalian and vertebrate species. He is deeply interested in mapping both coding and non-coding genome sequence variation to phenotype differences, and in extracting specific genetic insights from high throughput sequencing measurements, in the contexts of development and developmental abnormalities.
