Matthew Young is a research fish biologist with the U.S. Geological Survey, and has been with the California Water Science Center since 2016.
He received his B.S. and Ph.D. degrees from the University of California, Davis. His work research is focused on interactions of native and non-native fishes with their environment, including novel ecosystem elements such as altered hydrology and proliferating non-native habitat engineers such as submersed aquatic vegetation. Currently he works in a variety of systems exploring relationships between native fishes and changes to their environment. This includes the spread of non-native species and potential displacement/competition, habitat alteration and the loss of underlying ecosystem processes, and the potential for habitat restoration to provide key mechanistic benefits to native fishes and other aquatic organisms.

Ecology and ecosystem impacts of submerged and floating aquatic vegetation in the Sacramento-San Joaquin Delta
Substantial increases in non-native aquatic vegetation have occurred in the upper San Francisco Estuary over the last 2 decades, largely from the explosive growth of a few submerged and floating aquatic plant species.

Terminal channels were historically a common feature of tidal delta ecosystems but have become increasingly rare as landscapes have been modified.
