Dr. X. Nancy Xu is an elected AAAS (American Association for the Advancement of Science) Fellow and Professor of Chemistry, Biochemistry, Biomedical Sciences and Biomedical Engineering at Old Dominion University (ODU). During her tenure at ODU, Dr. Xu has built a state-of-the-art interdisciplinary research laboratory, and successfully developed a nationally and internationally recognized and well-funded interdisciplinary research program at the intersection of chemistry, biology, engineering, and medicine. Dr. Xu has successfully directed NSF and NIH funded interdisciplinary research programs and she has demonstrated a track-record of accomplishments in successfully competing for highly prestigious federal research grants, including NSF NIRT, NSF BRAIN Initiative, NIH R01, and DoD MURI awards. Dr. Xu has pioneered the development of a set of powerful new nano biophotonics tools for biomedical applications, and she has made distinguished contributions to the fields of sensing, imaging, nanobiotechnology, and ultrasensitive bioanalysis. She is especially well recognized for her pioneering work in single nanoparticle optics, nano optical biosensors, single molecule detection, and single live cell imaging. Dr. Xu holds a world-wide patent on DNA Biosensors and has consistently published her work in high impact peer-reviewed journals such as Science, JACS, Nano Letter, ACS Nano, Nanoscale, Analytical Chemistry, Journal Physical Chemistry C, Journal Applied Physics, and J. Electrochemical Society.
