Walt Beyeler

Photograph of Walt BeyelerMr. Beyeler’s initial work, for the US Geological Survey and for Jacob’s Engineering  was in developing models of groundwater flow and transport, and in using those models to assess performance of radioactive waste disposal systems. At Sandia National Laboratories he has continued to develop models of transport processes for use in decision-making. These applications shared the challenge of evaluating decisions in the face of large uncertainty about system behavior and parameters. He has developed models of complex systems across numerous domains for use in understanding their failure modes and designing control and mitigation strategies. Focus area include banking and finance, agricultural supply networks, and energy production and distribution. His most recent work is in modeling disease transmission and control. Application contexts include evaluating strategies for pandemic influenza, detecting and countering epidemics in herd animals in Afghanistan, and improving medical laboratory systems to speed diagnosis of Ebola patients in West Africa.

Education
