Dr. Ryan left CCR in April 2021. Dr. Ryan was among the first to demonstrate asymmetric division of DNA in cancer. This process is thought to underpin how tumors self-renew and regenerate. Her studies examined the roles of the tumor microenvironment and p53 in regulating this process in lung cancer. Her lab oversaw an integrative and translational approach to lung cancer research, examining the genetic, environmental, and biological contributions to racial disparities in lung cancer incidence. Her research program also developed biomarkers for the early detection of lung cancer.
