Dr. Thomas (Tom) P. Barrera is currently Owner and President, LIB-X Consulting, where he provides engineering and educational services in the broad area of lithium-ion battery power systems. Previously, Tom was a Technical Fellow for The Boeing Co., Satellite Development Center (El Segundo, CA), where he led multidisciplinary teams in systems engineering of advanced space electrical power subsystem technologies. During his 19-year Boeing career, Tom provided missions operations support for the NASA Space Shuttle and International Space Station programs as well as battery expertise for the CST-100 Starliner, Space Launch System, numerous commercial and government LEO/GEO satellite systems, and various high-value proprietary programs. Before joining The Boeing Co., Tom served as a space battery R&D test engineer at The Aerospace Corporation and electrical power systems engineer at the NASA Lyndon B. Johnson Space Center. Tom currently serves as an industry member of the NASA Engineering and Safety Center and is on the advisory board for South 8 Technologies. Frequently invited to speak and lecture at domestic and international conferences, Tom has over 50 combined conference presentations and publications, including 3 US patents in the area of aviation battery safety. Dr. Barrera earned his PhD in chemical engineering from the University of California, Los Angeles (UCLA) with a minor in atmospheric chemistry and physics. He also served as a Postdoctoral Research Fellow in the department of materials science and engineering at UCLA. Tom earned his MS in industrial engineering and management sciences from Northwestern University, BS in chemical engineering (cum laude) and BA in mathematics–economics both from University of California, Santa Barbara. He is also an AIAA Associate Fellow, member-at-large for the Battery Division of the ECS, and member of Tau Beta Pi.
