Dr. Stegen completed a PhD at the University of Arizona in 2009 in Ecology and Evolutionary Biology, and spent two years as a U.S. National Science Foundation postdoctoral fellow before moving to Pacific Northwest National Laboratory (PNNL) in 2011 as Linus Pauling postdoctoral fellow. At PNNL he has transitioned to a senior research scientist with an emphasis on river corridor science, and also holds a joint appointment with Washington State University. A hallmark of his work is the development of ICON-based science to generate outcomes that are transferable across systems and mutually beneficial across stakeholders through intentional Integration, Coordination, Openness, and Networking. He co-founded ICON Science Cooperative (https://icon-science.pnnl.gov) to facilitate use of these principles and co-founded the ICON-based Worldwide Hydrobiogeochemistry Observation Network for Dynamic River Systems (WHONDRS; https://whondrs.pnnl.gov). These efforts are leading to large-scale synthesis and democratized access to data, instrumentation, and collegial networks. In this context, he focuses on linking detailed molecular properties of the chemistry and biology of river corridors to major physical drivers and disturbances, such as the progressive loss of surface water. A unique aspect of his technical approach is merging concepts, theories, and tools across disciplines, such as the integration of meta-community ecology with organic matter molecular chemistry.
