Research Interest Statement
Cathleen is an Isotope Geochemist, Science Educator, and Director of the Inorganic Analysis Facility in the Environmental and Occupational Health Sciences Institute at Rutgers University. She is also an adjunct professor in the Department of Earth and Planetary Sciences at Rutgers, and research mentor to undergraduate and graduate students in forensic toxicology, public health, and environmental exposure.
Her research interests span scales of both time and space, from preset-day surface processes related to environmental contamination, to ancient deep-Earth processes related to differentiation of Earth’s reservoirs. Her work employs field and laboratory techniques using isotope geochemistry, in-situ chemical analysis, and petrology to answer questions related to chemical cycling, biomarkers of human heavy metal exposure, global climate change, and the evolution of Earth’s mantle. Most recently, her research aims to address emerging questions at the intersection of environmental exposure and public health, with a focus on environmental justice. Her broad research interests are motivated by the adaptability of geochemistry to various Earth systems, and the development of novel techniques to assess environmental exposure and human health in at-risk populations.

Cathleen is also deeply passionate about science education, and seeks opportunities to establish relationships between the university and K-12 schools to provide research and training opportunities for both teachers and their students. Her laboratory is also committed to supporting an equitable and diverse scientific community, and aims to foster an inclusive environment where all people feel safe, valued, and respected.
