Dr. Tisherman joined PSE in 2021 where her work focuses on the environmental impact of oil and gas development on water resources. During her PhD, Dr. Tisherman researched the transport and fate of trace metal-contaminated sediments. Specifically, her research focused on the mobilization of contaminated sediments from mining, oil and gas production, and agriculture in the US and in China.

Through her research, Dr. Tisherman has worked to create a chemical framework that differentiates between various sources of oil and gas water contamination. Prior to graduate school, Dr. Tisherman researched the impacts of unconventional drilling on surface water in Chengdu, China as a U.S. Fulbright Scholar.

Dr. Tisherman received her BA in Environmental Studies from Connecticut College and received her PhD in Geology and Environmental Science from the University of Pittsburgh in January 2022.
