Research Summary

We study the interplay of gene expression and genome organization. Our work focuses on understanding how large molecular machineries involved in genome organization and gene transcription regulate each others’ function to ultimately determine cell fate and identity. We employ a broad range of approaches including single-particle cryo-electron microscopy (cryo-EM), X-ray crystallography, biochemistry, and genetics to mechanistically understand how these molecular assemblies regulate each other across molecular scales.
