Brian Bergamaschi


Dr. Brian Bergamaschi is a research biogeochemist with the USGS California Water Science Center and adjunct Faculty at California State University Sacramento.  He received a Ph.D. in Chemical Oceanography from the University of Washington, in Seattle, WA, where he specialized in analyzing the sources and fates of natural organic material in the environment.  His main interests are in understanding processes of carbon cycling in aquatic environments and related biogeochemical processes. His particular emphasis is on developing methods for quantifying the interactions between physical and biogeochemical processes. His research ranges in scale from light-mediated molecular transformations, to tidally-driven wetland fluxes, to effects of changing continental-scale fluxes on coastal carbon processes. His current projects largely focus on the effects of wetland restoration on aquatic habitat quality and carbon cycling.
