Dr. Jonathan Fisher

Dr. Jonathan Fisher is the Chief Business Officer of Fifth Gait Technologies, Inc., a minority woman-owned small business specializing in system survivability, hardened systems, custom advanced sensor systems, operational environment and effects, modeling and simulation, test and evaluation, and program execution and mission assurance. 

Fifth Gait Technologies, Inc. is headquartered in Santa Barbara, California and has offices and test centers* in Torrance, California; Colorado Springs, Colorado*; Huntsville, Alabama*; Raleigh, North Carolina and Ecuador.

Fisher is responsible for providing corporate infrastructure, policies and procedures. He provides subject matter expertise in the areas of modeling, simulation, and testing of space radiation and nuclear weapons effects (X-rays, neutrons, Mechanical, Optical, Electronic, and Transport Phenomena). He is engaged in systems engineering and design of electro-optical and structural systems, radiation hardening of optical, electro-optical, electronic, and structural systems, and definition of space and nuclear weapons radiation environments. 

Prior to his position at Fifth Gait Technologies, Inc., Fisher served as the director and principal investigator (PI) at GH Systems and scientist and principal investigator at Mission Research Corporation. He led the Department of Defense Rapid Innovation Funded X-ray Transport and Radiation Analysis (XTRRA) Toolkit Program that lead to the development and verification testing at LLNL’s National Ignition Facility and SNL’s Z Facility. Fisher was the PI for the Missile Defense Agency’s Hardened Mirror Technology program, the Optical Component outside user test at the National Ignition Facility, and development of the Space Ionizing Radiation Environment and Effects toolkit (an evolution of CREME-96), Neutron Induced Upset Toolkit, NWETran, NWETool2, and other models.

 He has led joint agency cold X-ray tests, supported the development of the DTRA developed DoD Satellite System Natural & Nuclear Environments Standard and MDA’s High Altitude Exoatmospheric Nuclear Survivability Standard, and provided expertise and led efforts on optical component and band pass filter hardening, boost vehicle design and high-altitude defense systems.

Fisher has refereed, invited and authored/co-authored a number of papers such as the “New Space Radiation Environment Model for Missile and Space Systems.” Presented at the 2015 HEART Technical Interchange Meeting (Chantilly, VA). Chantilly, VA. He was awarded Best Paper at the 2010 and 1999 HEART Conferences.

Fisher holds a Doctor of Philosophy in Applied Physics from Alabama A&M University and a Master of Science in Physics and a Bachelor of Science in Applied Physics from Eastern Kentucky University. He is a member of the American Physical Society, a senior member of IEEE-Nuclear Science Society, and the HEART Society-Steering Group Chair.
