Susan Bailey

(970) 491-2944 |

Dr. Bailey is a professor and a cancer molecular biologist in the Department of Environmental and Radiological Health Sciences (ERHS). Her current research program, funded primarily by NASA, focuses on the role of chromosomes and telomeres (the ends of chromosomes) in cancer and other human disease states (e.g., cardiovascular disease). Studies focus on interactions between telomeres and DNA repair, with the ultimate goal of shedding light on a key issue in these increasingly overlapping fields—how cells distinguish between natural chromosomal termini and broken DNA ends. Such studies also impact investigation of telomere length maintenance by telomerase as an informative biomarker of biological aging, and therefore disease risk, which is influenced by a variety of lifestyle factors, including stress (e.g., nutritional, psychological, physical) and environmental exposures (e.g., UV and ionizing radiations).
