    Collapse Overview 
    Collapse overview
    My research has focused on the development of radio-protective drugs for use in the prevention of radiation-induced genomic instability and subsequent processes leading to cancer development. Specifically, studies are directed at very low dose radiation and select phosphorothioate drug exposures to induce adaptive responses affecting genomic instability development.
