Research Summary
The Kron laboratory is a diverse and collaborative group of cell biologists, geneticists, biochemists, chemists and computer scientists. Our current basic research and technology efforts include 1) defining roles for chromatin dynamics and cell cycle regulation in DNA damage checkpoint response and cellular senescence, 2) dissecting cross-talk between metabolism and DNA damage response, 3) developing novel molecular assays to interrogate cell signaling in cancer, and 4) implementing novel mass spectrometry approaches to enable quantitative proteomics. We also pursue translational projects directed at 1) discovering inhibitors of cellular response to DNA double strand breaks as an approach to radiosensitization, 2) examining DNA damage and repair in tissues and tumors, and 3) exploiting DNA damage responses to induce anti-tumor immune responses.
