Walt
Computational Environmental Scientist/Hydrogeologist

Hydrogeologist with almost 30 years of professional experience, including roles as a research scientist with Lawrence Livermore National Laboratory, California, USA, and as a consultant for environmental and water supply projects. His primary interests involve simulation of flow, transport, and chemical processes in groundwater and soil systems, and scientific programming to support quantitative data analysis and development of customized simulation tools using Python and Julia. His modeling expertise includes geochemical/reactive transport models (PHREEQC/PHAST), groundwater flow (MODFLOW), flow and transport through unsaturated soils (HYDRUS, VS2DT), as well as multiphase flow through porous media (custom-developed simulation tools). He holds a Ph.D. from the University of California, Berkeley, and is a registered Professional Geologist in California, USA.
