Damon Runyon Researchers

Dr. von Diezmann is a biophysicist who studies how cells regulate the pathway used to repair broken DNA. Errors in specific DNA repair pathways are an early step in the development of many cancers, such as with defects in homologous recombination for breast, ovarian, and pancreatic cancers. The Diezmann lab uses high-resolution microscopy techniques to visualize the process by which DNA breaks are designated for specific repair fates, working primarily in live meiotic nuclei of the model organism C. elegans. By elucidating the mechanisms by which protein assemblies form and transmit information along chromosomes and throughout the nucleus, her lab will help provide a foundation for the development of novel chemotherapies based on modulating the DNA damage response.
