      • Jan 2020 - Present

      • Originated Precision Lethality project involving high-resolution 3-D modeling of targets, very fast predictive lethality and weapon effectiveness analysis, and improved warhead design and delivery methods. This new approach was also focused on minimizing warhead costs and optimizing the type and extent of target damage. Targets included armored vehicles, radars, missile systems, boats, drones, mine fields, and apartment buildings. • Developed an original approach to quickly predict the effectiveness of small warheads. • Analyzed Russian and Ukrainian (native speaker) open literature on the best military practices and lessons learned during the Russian-Ukrainian war of 2014-present. This included advanced warhead design with multiple shaped charges. • Lead a team of experts from the UK, Canada, Australia, and the USA developing small smart warheads. • Originated a program with AFRL involving directed water plume energy vs. bridge structures. Optimized submerged charge and its position. Analyzed the use of bombs, missiles, and drones. Designed and implemented a new DoD fast-running predictive analytical tool. • Successfully worked with the Air Force Program Office in Utah on the improved arena tests for aging bombs. Analyzed experimental data, and proposed refinements to arena tests. Derived new scaling relations for the equivalent charge weight produced in different climatic conditions. Discovered and characterized the influence of atmospheric humidity and pressure on the equivalent explosive weight. • Discovered and described super-fast electromagnetic waves produced by fuzes and warheads. Found a new way of pinpointing the fuze location. • Helped younger employees understand structural dynamics, material behavior, and how to interpret results of their computer simulations. • Studied advanced proposal- and report-writing methods. These methods have significantly, at least 10 times, increased funding amounts and the satisfaction of program managers. Show less

Invented a fiberoptic sensor system to monitor the deformation and health of the rail gun. • Proposed original conceptual design for the railgun terminal system. Performed modeling and calculations for the penetration depth of hypervelocity projectiles in the sand. The NSWCDD railgun terminal range was built based on this design. • Ran analytical, finite element, and smooth particle models. Developed a new failure criterion for fluid-filled submunitions with application to missile defense. • Evaluated SBIR proposals submitted to the Missile Defense Agency. Acted as Contracting Officer Representative to the SBIR projects including lightweight composite armor for missile canisters. • Served as a member of the Invention Evaluation Board of the NSWC, Dahlgren, VA.

      Performed nonlinear finite element modeling of impact with sliding interfaces and failure mode II to mode I transition in pre-notched steel plates. Used 2-D rate-dependent elastic-thermoviscoplastic material models. 3-D modeling (DYNA3D) of reverse buckling phenomena in elastic-plastic plates made of a material with strain and strain rate hardening, thermal softening, and randomly distributed defects. Proposed and demonstrated via finite element simulation (contact-impact model with deformable boundaries sliding with friction and erosion), that high-speed ceramic rods exhibit self-sharpening and multiple impacts, and can perforate steel and tungsten targets (“Penetration/Perforation of Aluminum, Steel and Tungsten Plates by Ceramic Rods,” 1998, Int.
