Dr. Le's group actively pursues research involving bioanalytical chemistry and environmental health sciences. Current projects include (i) analytical techniques and assays for molecules of environmental and biological significance; (ii) arsenic speciation, exposure, metabolism, and health effects; (iii) DNA damage and protein biomarkers; (iv) environmental health; and (v) water and food safety. The ultrasensitive techniques and assays enable studies of the environment and human health. This group enjoys extensive collaborations with multidisciplinary research groups both on campus and internationally.
