Areas of Research

Area of Focus
  • Mechanisms of DNA double strand break repair
Summary of Research

The main focus of our lab is to understand how cells detect and repair DNA damage induced by ionizing radiation and chemotherapeutic drugs. Of particular interest are the roles of the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) and Ataxia Telangiectasia Mutated (ATM) in the cellular response to DNA damage. A major goal is to use our knowledge of the DNA damage response to develop novel approaches to improve cancer treatment. We are currently exploring the use of poly ADP ribose polymerase (PARP) inhibitors to target ATM deficient cancers and the role of PI3 kinase in cisplatin resistance.

Our DNA is under constant threat from DNA damaging agents. Paradoxically DNA damaging agents such as ionizing radiation and chemotherapy are used to treat cancer. Our lab studies how cells respond to DNA damage induced by ionizing radiation, such as that used to treat cancer patients. Our main research focus is the mechanism of non-homologous end joining (NHEJ), which is the major pathway used by human cells to repair DNA damage caused by ionizing radiation. We discovered some of the main players in this pathway over 30 years ago and my lab has made major contributions to understanding the mechanism of NHEJ. We have published over 200 research articles in this area that have been cited over 25,000 times, with an h-index of 89. One of our most recent contributions was, in collaboration with Dr. Yuan He of Northwestern University, USA, determining the structure of  multi-protein-DNA NHEJ complexes using cryo-electron microscopy. These findings were published in the prestigious journal Nature in 2021.
