Boris Faybishenko is a staff scientist of the Earth Sciences Division of Lawrence Berkeley National Laboratory, Berkeley. He conducted field site characterization, monitoring, and modeling of coupled water and gas flow and chemical transport (organics, radionuclides, and metals) in unsaturated (vadose zone) and saturated (groundwater) soils and fractured rock at organically and radioactively contaminated sites. His research interests include the development of innovative in situ site characterization and monitoring tools, conceptual and numerical modeling, using methods of nonlinear dynamics, chaos theory, fuzzy systems, and stochastic modeling of flow and transport in the vadose zone and groundwater, as well as time-series climatic analysis.
