In order to study the 3D DNA structures which regulate contacts between cis-regulatory elements (CREs) and their target transcribed elements (TEs), we are developing a super-resolution imaging approaches capable of resolving tens to hundreds of individual CREs, TEs, and intervening sequence in single cells of sectioned embryonic tissue and cultured cells at better than 20 nm resolution. We are applying this approach […]
Differences in gene expression arise due to differences in how accessible the sequence encoding a gene is to the transcription machinery of the cell. While we know much about the structure of DNA at small lengths scales (<1 kilobase) and at large length scales (whole chromosomes), we understand little about its organization at the intermediate scale of kilobases to megabases.

Lab renovations are planned to start in September 2016. Microscope assembly and basic experiments should start in November. We’ll be accepting rotation students in both winter and spring quarters!
