Biographical Sketch

I received a B.Sc in 1966 and M.Sc. in 1967 from The Ohio State University, studying changes in the ultrastructure of organelles in insect hemocytes during hemolymph coagulation.  I obtained a Ph.D. in 1973 from the Department of Biology, Johns Hopkins University, conducting research on the structure of chromatin using biophysical methods.  As a post-doctoral fellow in the laboratory of Norman Davidson at Caltech, I developed methods to map gene organization using molecular and biochemical methods to label genes detectable by electron microscopy.  I then joined Bob Angerer to form a research team at the University of Rochester studying the molecular mechanisms that regulate early development of the sea urchin embryo.  We developed the technique of in situ hybridization to detect mRNAs using RNA probes and applied this approach to determine when and where the early embryonic territories in the sea urchin are established.  Our studies led to the identification of transcription factors regulating ectoderm development through cis-regulatory analyses of genes expressed in this tissue.  After moving to NIH, I became the head of the Developmental Mechanisms Section and Bob became the Scientific Director of NIDCR.  Our research group continues to investigate early patterning mechanisms in the sea urchin embryo focusing on the neuroectoderm and endomesoderm.  We developed a microarray from the newly obtained sea urchin genome sequence for genome-wide screens to identify genes important in determining the regulatory states of early embryonic cells in the presumptive ectoderm and to explore how these states are altered by intercellular signals.
