Dr. Michael Friedel is a senior computational scientist at Pacific Northwest National Laboratory. Prior to this role, Dr. Friedel was associate researcher at Semeion Institute, IT; the environmental data analytics science leader at Lincoln Agritech, Lincoln University, NZ; senior research hydro-geophysicist at the Institute of Geological and Nuclear Science, NZ; and senior research geophysicist, senior research hydrologist, and supervisory hydrologist with the US Geological Survey.

Dr. Friedel has extensive experience in the development and application of methods and workflows that discover, quantify, and predict linkages and their response to climate, hydrologic and biogeochemical cycles across spatiotemporal scales. His research employs artificial-adaptive systems (evolutionary, machine-learning, learn-heuristics, metamodels, multimodal transfer learning); process-based (traditional/joint numerical) and statistical (Bayesian, frequentist) methods. Dr. Friedel designs, collects, and integrates big data including direct (physical, chemical, biological) and indirect (geophysical and remote sensing) measurements across multiscale environmental networks (space, airborne, surface, borehole) to improve theory, scalability, and predictability.
