Undergraduate Summer Fellowship, Centers for Disease Control and Prevention, National Center for Environmental Health, Division of Laboratory Sciences. The candidate will participate in projects associated with developing and applying new methods to characterize and quantitate biochemical markers that are relevant in environmental exposures and chronic diseases. This includes assessing a variety of markers in biologic specimens (such as serum or urine) and developing reference materials. The candidate will be part of a multidisciplinary team and will work with state-of-the-art equipment on topics relevant to public health. DLS offers a stimulating environment that enables summer Fellows to learn about applied analytical chemistry and to enhance their knowledge of public health.
