Dr. Joseph Holomuzki is the Western Branch Chief of the National Research Program for Water Resources in the U.S. Geological Survey in Menlo Park, CA. The Branch has ~65 highly-skilled  scientists studying topics such as surface-water hydrology and chemistry, ground-water hydrology and chemistry, erosional processes and sediment transport, and biological and microbiological processes that affect water quality and ecosystem health. His research focuses on community dynamics in riverine and wetland ecosystems in New Zealand and the United States (mainly the Laurentian Great Lakes region and northern California). In New Zealand, he studies how flooding and species interactions (typically predation by fishes and competition for benthic algae) regulate populations of freshwater macroinvertebrates. His research in Ohio centers on how invasive plants alter food web structure and ecosystem function in Lake Erie coastal wetlands. He has worked closely with the Ohio Department of Natural Resources to provide baseline data on practical economic strategies to limit expansion of Phragmites australis (common reed) and to restore biodiversity in reed-dominated wetlands. His interests also cover how food webs are structured in rivers under Mediterranean climates in California. Dr. Holomuzki has published nearly 60 peer-reviewed research papers and book chapters, served on review panels or reviewed proposals for the National Science Foundation and Sea Grant, reviewed manuscripts for 26 different journals, and served on the editorial board for Copeia (1994–1998) and for the Journal of the North American Benthological Society (J-NABS; now titled Freshwater Science) (2001–2004). His professional-society service has centered mainly on operations of the Society for Freshwater Science (SFS) (formerly known as the North American Benthological Society [NABS]), where he served as President from 2011 to 2012. Prior to coming to the USGS, he was in academia, where he was honored with several teaching awards, including the Ohio State University Alumni Award for Distinguished Teaching in 2011.
