Mr. Todd Roy has recently joined LLNL and currently serves as a senior defense systems analyst in the Systems Analysis Group in ODC. Mr. Roy has over 33 years of experience in the aerospace and defense industry in the research, development, testing, and fielding of advanced technologies for the DOD and other agencies.

Mr. Roy was employed by Lockheed Martin (LM) from 1993 to 2018 supporting their missile development lines of business. Starting in 2014, he served as the Terminal High Altitude Area Defense (THAAD) Chief Scientist at LM, leading the development of spiral technologies for the THAAD weapon system to increase near-term counter-hypersonic engagement capability. This included development of technologies for key components across the weapon system. In addition, he led the development of alternate and next generation defeat approaches and interceptor concepts to address the hypersonic threat. This research included development of a new highly agile interceptor/kill vehicle that provides hit-to-kill capability against dynamic threats for large area terminal tier defense. This concept is under evaluation by the Missile Defense Agency (MDA) under the Advanced Threat Missile Defense Analysis of Alternatives.

From 1993 to 2014, Mr. Roy served as the principal investigator for numerous Internal and Contract Research and Development (IRAD and CRAD) initiatives developing next generation technologies to further expand ballistic missile defense (BMD) capabilities across all phases of engagement. These efforts included comprehensive study and characterization of the threat capabilities to inform existing and planned BMD investments and roadmaps, as well as novel defeat approaches for left-of and right-of-launch. Mr. Roy served as the Chief Engineer for LM under the MDA Project Hercules Program responsible for developing advanced discrimination algorithms and processing. He also served as a member of MDA and DOD technical oversight committees supporting Project Hercules and other related research and development activities.

From 1984 to 1993, Mr. Roy served as a principal engineer developing acoustic signal processing algorithms for the U.S. Army Bat Anti-tank weapon and successfully demonstrated these algorithms in live testing at China Lake. Prior to that, he developed an IRAD test facility to test and characterize advanced Ring Laser Gyroscopes for application to the MX, Small ICBM, and eMaRV missile systems.

Mr. Roy has a BSEE from Louisiana State University and his research interests include missile threat assessment, phenomenology, and signal processing.
