Biography

Scott Waichler has extensive experience in processing, analyzing, and visualizing hydrologic data. He is a scientist/programmer/task leader who works in a variety of hydrology subfields including groundwater flow and transport, surface water flow, watershed hydrology, meteorology, and statistics. He combines scientific subject matter knowledge with skill in data processing, visualization, statistical methods, and publishing experience to successfully serve projects. Scott is an expert in the R scripting language and also works with Python and VisIt. He has simulated hydrologic systems with the models STOMP, DHSVM, MASS1, and others.
