Tim Filley is a professor of stable isotope biogeochemistry in the Department of Earth, Atmospheric and Planetary Sciences. He is also U.S. Director of the U.S.-China EcoPartnership for Environmental Sustainability, as well as the Co-Director of the Arequipa Nexus Institute. Broadly, Filley’s research focuses on the fundamental processes controlling the cycling of carbon and nitrogen in soil, litter, and streams within natural and managed ecosystems, and the implications of such biogeochemistry to the fate of emerging pollutants. Using natural abundance and highly enriched stable isotopes and biomarker tools his group investigates how perturbations to ecosystems (e.g., woody plant encroachment, invasive species, storm events and intensive management) interact with soil and microbial properties to stabilize or destabilize soil organic matter. A primary goal of this work is to develop a stronger scientific basis for understanding the vulnerability and resilience of soil organic matter to intensive management. Filley received his B.S., chemistry, from Loyola University of Chicago, and his Ph.D. in isotope geochemistry from the Pennsylvania State University.

Robby joined C4E in June 2019 after relocating to West Lafayette from Austin, Texas, where he was a Research Assistant for the Consulate General of Ireland for four years. Prior to that role, Robby was a Legislative Aide in the Texas House of Representatives for the 83rd and 84th legislative sessions. He graduated with a B.A. in Geography from the University of Texas at Austin. During his time as an undergraduate, Robby was selected to the Bill Archer Fellowship Program, which allowed him to spend part of his senior year in Washington, D.C. as an Environmental Policy Intern for The Wilderness Society. Outside of work you can find him watching baseball, riding his motorcycle, and taking weekend trips with his wife, Elizabeth.
