Dave Engel is a Senior Research Scientist in the Computational Mathematics Group of the Fundamental and Computational Sciences Directorate of the Pacific Northwest National Laboratory. He has been working on modeling and simulation projects for the past 25 years. Recently, he has been focusing on combining state-of-the-art statistical, mathematical, and computational methods in sensitivity analysis, uncertainty quantification, and optimization into iterative approximation techniques (including high performance computing), and applying them to the Hanford Groundwater modeling effort.
