## Biography

Aaron Luttman is an advisor in Physical Detection Systems and Deployment Division at PNNL, where he operates at the nexus of bringing the latest developments in mathematics and data science to concrete national security applications, establishing and leading diverse and collaborative research teams, and engaging government sponsors to grow our mission.

Luttman has worked in industry, academia, and the Department of Energy (DOE) enterprise, with research spanning machine learning, computer vision, multisensor networks, landscape ecology, ocean flow dynamics, nuclear fusion, mathematical models for novel measurement systems, and commutative Banach algebras. He is also active in the broader scientific community. He was a featured mathematician in the book *101 Careers in Mathematics*, *3rd Ed.*, having delivered more than 100 invited and conference research presentations. Luttman has served as a distinguished lecturer for the Mathematical Association of America (MAA) and visiting lecturer for the Society of Industrial and Applied Mathematics. He has published more than 40 peer-reviewed journal articles and is an industrial partner to the Preparations for Industrial Careers in Mathematics program. Luttman serves as an officer of the MAA’s Special Interest Group on the mathematics of business, industry, and government. He also serves on the industrial advisory board to the graduate program in computational mathematics at Embry-Riddle Aeronautical University.
