I joined Interdisciplinary graduate program in human toxicology in 2009. After completing three lab rotations, I joined Dr. Robertson’s lab in June 2010. My research area is inhalation toxicity of lower chlorinated PCBs. Taking a prototypical congener (PCB3), I’m looking at different phase II metabolites in urine in order to identify a potential biomarker metabolite for assessment of environmental exposure to lower chlorinated PCBs. Additionally, I’m also looking at genotoxicity, specifically mutation frequency in lungs, following sub-chronic inhalation of PCB3 in a rat model.

Thesis Title: Urinary sulfate conjugates are markers of inhalation exposure to 4-chlorobiphenyl (PCB3)
