Program manager and technical/professional expert for Climate Change Observation, Research and Decision Support for the U.S. Geological Survey. Current assigned programs include: (1) Coordinator for the design, implementation, and data synthesis of a nationally-integrated climate effects observation and research network; (2) Project coordinator for the Yukon River, Platte River, and Upper Colorado River Basin design and science planning teams that are implementing the CEN in these regions; (3) DOI representative to the Climate Experts Group of the Arctic Monitoring and Assessment Program (AMAP) and the Arctic Observing Network (AON); (4) backup Head of Delegation for the US for AMAP; (5) Co-chair of the DOI Integrated Observations and Data Management Working Group and technical report lead for development of the DOI Integrated Observations implementation plan; (6) lead author for the AMAP Trends and Effects Program 5-year plan for the 7 nations of the Arctic Council.

Principal investigator in the Watershed Research Section of the New York Water Science Center. Research investigations focused primarily on basic and applied problems relating to biogeochemical processes controlling the quality and sources of surface waters and the regional extrapolation of knowledge gained to the surrounding region. The functions of this position were to conduct hydrologic and biogeochemical research, develop new research ideas, and provide research and monitoring expertise in the specific areas of water chemistry, hydrology, geochemistry and geomorphology, and the effects of climate on the above, to be applied to interdisciplinary research which advances the current understanding of watershed processes and function. The products were also being used to determine the extent and magnitude of terrestrial and aquatic responses to acidic deposition and climate change, and for decision support in developing appropriate adaptation management strategies. Presented over 50 invited talks and numerous presented talks since the mid-1990s on this work, and published 17 lead-author and 36 co-authored papers. Served as a principal author of both the CENR Framework for Environmental Monitoring and Related Research (1997), and the DOI Climate Change Science Task Force Science Strategy (2008).Awards include the following: Dept. of Interior Meritorious Service Award, 2000. Received in recognition of my contributions to the science of acidic deposition effects on forested landscapes, and my contributions to public education. USDA Certificate of Merit, 2001. Received in recognition of my leadership and technical contributions to the development of collaborative research with the Forest Service in the Delaware River Basin.USGS Benchmark Award: Received in April 1998 for enhancing public education of water resource issues through the outreach partnership with the YMCA and local schools.
