I am a policy and technical expert specializing in the role of science in shaping multilateral cooperation on the environment. Trained as a geologist, I began my career working on transboundary environmental issues as a U.S. Peace Corps volunteer in Ukraine. After gaining experience on contaminated site remediation as a private consultant, I joined the U.S. Environmental Protection Agency Office of International Affairs, where I served on the U.S. delegation negotiating the Minamata Convention on Mercury. In 2014, I joined the UNEP Chemicals and Waste Branch. My work includes managing projects on reducing mercury use in artisanal mining and other sectors, facilitating scientific and policy assessments on mercury and other chemicals, and coordinating activities with the Global Mercury Partnership.
