SciVal Experts Research Profile


MD , New York University , 1984
MPH , Johns Hopkins University , 1991


Dr. Weaver’s research interests involve the use of molecular epidemiology tools in the evaluation of populations exposed to occupational and environmental chemicals. The validation of exposure and early biological effect markers to improve clinical evaluation and medical surveillance is a primary focus. Identification of susceptible populations is an additional goal.

Her primary area of research is the impact of occupational and environmental toxicants on the kidney. Currently, she is studying clinical and early biological effect markers (urinary retinol-binding protein and N-acetyl-beta-D-glucosaminidase (NAG)) for the renal system in lead workers in South Korea. This longitudinal study is evaluating the effects of lead and cadmium exposure on a range of renal outcomes. Interaction with genetic susceptibility factors and chronic diseases, such as hypertension, is also a focus in this work. She has also studied biomarkers for benzene exposure in urban populations, including children.

Dr. Weaver’s clinical activities also involve biomarker applications, thus complimenting her research. These activities have included management of a medical surveillance program for cadmium exposed workers in which blood and urine cadmium and beta-2 microglobulin were monitored. In addition, she was a co-investigator in a medical surveillance program for former workers at Los Alamos National Laboratory. This project involves workers with many previous exposures and uses the lymphocyte proliferation test to assess for presence of sensitization from previous beryllium exposure.
