Our Research

Our laboratory studies the spatial organization of the genome, with implications for gene regulation, genome integrity, and diseases such as cancer, aging, and neurodevelopmental disorders. We use Drosophila and mammals in combination with cellular, molecular, genetic, and computational tools to elucidate how chromosomes are functionally organized in 3-D space and time. We also develop and utilize new technologies that use fluorescent in situ hybridization (FISH) to interrogate chromosome positioning at single-cell resolution. These include a pipeline for high-throughput FISH (Hi-FISH), and a new type of probe, called Oligopaints, which reduces the cost and increases the resolution of FISH.

Chromosome Folding

The major feature that stands out in the nucleus of all metazoan genomes are the chromosome territories (CTs), which have nonrandom radial positions that are conserved through evolution. We are using our custom Oligopaint FISH probes to identify signatures of chromosome arrangement 

SMC Complexes and Disease

Cornelia de Lange Syndrome (CdLS) is a developmental disorder characterized by congenital abnormalities, intellectual disability, and multi-system clinical symptoms including congenital heart disease. The disorder typically manifests due to mutations in
