Key words: Developmental genomics
Research in the lab focuses on how a single genome gives rise to a variety of cell types and body parts during development. We use Drosophila as a model organism to investigate (1) how transcription factors access DNA to regulate complex patterns of gene expression, and (2) how post-translational modification of histones contributes to maintenance of gene expression programs over time. We combine genomic approaches (e.g. chromatin immunoprecipitation followed by high-throughput sequencing) withDrosophila genetics and transgenesis to address both of these questions. Defects in cell fate specification and maintenance of cell identity often occur in human diseases, including cancer.
