Since joining Chevron in 2007, her interests have lied in advanced analytical characterization of organic compounds in a variety of matrices. Over the past eight years, she has collaborated with researchers from various disciplines (e.g., biochemistry, toxicology, environmental science, and hydrogeology) to better understand the composition of and the risk posed by organics in the groundwater at historic petroleum release sites. In addition to frequently presenting her research results to audiences at technical conferences, she is also passionate about describing her work to elementary, middle and high school students to promote STEM (science, technology, engineering, and math). Rachel has over twenty publications in peer-reviewed journals, two patents, and serves as a reviewer for multiple technical publications including Environmental Science and Technology (an ACS journal), and Journal of Chromatography. She has been a contributor and active member of the ITRC TPH Risk Evaluation at Petroleum Contaminated Sites team.
