I am broadly interested in the use of field monitoring studies and simple mechanistic models to describe and understand pollutant fate and implications for human health. My past research has focused on environmental distribution and bioaccumulation of legacy pollutants (including mercury, PCBs, PAHs, PBDEs, and legacy pesticides) in California waters. My PhD research focuses on applying models to describe chemical fate of antibiotics, consequent spread of antibiotic resistance, and human health risk implications. I am also collaborating with the Systems Approach to Green Energy IGERT Program, studying potential health impacts of hydraulic fracturing (“fracking”) and other unconventional petroleum development technologies.

Why I chose the Berkeley EHS program

I chose Berkeley because of the tremendous academic freedom and flexibility of the program, and intellectual resources available at Berkeley. At UC Berkeley it is expected for us to collaborate with other students and faculty across campus. EHS program PhD students are also encouraged to develop their own independent research agenda, and the program is designed to foster this.
