Research
Research in the Ellenberger laboratory focuses on the molecular structures and cellular functions of proteins that replicate DNA, repair chemical damage, and regulate chromatin structure. These enzymes and regulatory proteins ensure the faithful transmission of our genetic blueprint to future generations.
