Dr. Odenwald received his Ph.D. degree in Biology from Johns Hopkins University. His postdoctoral work on the functional analysis of the murine homeobox gene Hox A.5 was carried out in the laboratory of Robert Lazzerini at the NINDS. In 1990, he established the Neurogenetics Unit in the Laboratory of Neurochemistry, NINDS, where he has pursued the identification and functional analysis of neuronal-identity networks that control stem cell lineage development in the CNS. Dr. Odenwald became Chief of the Neural Cell-Fate Determinants Section at the NINDS, where he studied the role of transcription factor regulatory networks that participate in the temporal development of Drosophila CNS ganglia. Recently, his lab has developed a set of comparative genomics tools to aid in the evolutionary analysis of gene regulatory DNA and viral evolution. Dr. Odenwald became a Scientist Emeritus in 2017.

In a developing nervous system, the precise timing of cell identity decisions is most likely under the combinatorial control of cell-extrinsic and cell-intrinsic regulatory inputs. To understand how these orchestrated events collectively produce a functioning nervous system it is necessary to characterize the genetic circuitry underlying the patterning of cell-fate determining events. Given the remarkable gene conservation observed among all metazoa, we believe that understanding the molecular details of Drosophila CNS lineage development will have broad implications for vertebrate neurogenesis. Our studies reveal that there exists a cell-identity regulatory network that acts temporally during the formation of all CNS ganglia. We have discovered that during neural precursor cell lineage development most neuroblasts undergo sequential transitions in the expression of a set of transcription factors: As a result sequentially formed neuronal subpopulations arise that are marked by the expression of one of these factors. Given the global nature of this regulatory cascade, we hypothesize that these expression domains represent fundamental branch points in the developmental programs that control cell-fate decisions in all CNS ganglia.

To gain insight into how neuroblasts transition from one developmental program to the next, we have focused our research efforts on the identification and functional analysis of gene regulatory DNA regions, called enhancers, that control the expression of these transcription factor genes. Thus far, we have discovered that each factor is regulated by multiple enhancers that control different aspects of their expression (view examples at our cisPatterns web site). Using multi-genome DNA alignment programs, developed by in our lab: EvoPrinter and cis-Decoder, we have taken advantage of the cumulative evolutionary DNA sequence divergence that exists among species to identify highly conserved DNA sequences within each of the enhancers. Mutational analysis of these sequences reveals that each is required by normal gene control. Currently, we are adapting our comparative genomic tools so other scientists can use them to study vertebrate enhancers.
