Biography

Matthew Hoffman has over 18 years of experience in project leadership and in simulation, optimization and data analytics of complex systems for national security. He received his MS in applied mathematics from the New Mexico Institute of Mining and Technology, where his work on hybrid (continuous-discrete) dynamical systems involved extensive improvements to a power systems dynamics research code. At Sandia he has focused on applied optimization research, and in 2015 he was named an INFORMS Franz Edelman Laureate for leading work “representative of the best applications of analytical decision making in the world” optimizing multi-billion-dollar strategic investment decisions for the US Army. For Sandia’s EMP Grand Challenge he led work (1) characterizing cascading failure modes of the power grid in response to high-altitude electromagnetic pulse and (2) optimizing the post-cascade stability and operating state of the grid prior to restoration from severe emergencies. He was also the initial PI of a recent R&D project on stochastic resilience planning optimization for the grid incorporating dynamic effects of major disruptions.
