Area of Interest
In the broadest terms, we seek to understand how information is encoded and dynamically utilized in living eukaryotic genomes. We focus specifically on those areas of the genome that regulate chromosomal functions such as transcription, DNA replication and repair, recombination, and chromosome segregation.
The projects in my laboratory are united by the scientific goal of understanding relationships between chromatin, transcription factor targeting, and gene expression. We use three biological systems: (1) S. cerevisiae (hereafter "yeast") to address basic molecular mechanisms; (2) C. elegans to test the importance of those mechanisms in a simple multicellular organism; and (3) cell lines and clinical samples to directly interrogate chromatin function in human development and disease. The genomes of these organisms span three orders of magnitude in size (12 Mb, 100 Mb, and 3000 Mb respectively) and a wide range of genome complexity (~50% coding, ~25% coding, and ~1.5% coding respectively). Use of these systems, with C. elegans serving as a "stepping stone" to bridge yeast and human studies, permits us to quickly bring concepts discovered in model systems to medical relevance.
