Karen Taminger
Karen Taminger
NASA Langley Research Center
2023 BIG Idea Challenge Co-Chair


Karen Taminger started her career at NASA Langley Research Center as a co-op student in 1986 and full-time as a Materials Research Engineer since 1989. She develops advanced metals and processing methods and leads multidisciplinary teams. She served as the technical lead for structural efficiency in the Advanced Air Transport Technology project for the past 16 years and recently led LaRC’s fabrication of the backplate for the Exploration Extravehicular Mobility Unit spacesuits. Since 2000, she has led LaRC’s metal additive manufacturing efforts through a variety of center innovation, aeronautics, for space and in-space programs, inventing and maturing the Electron Beam Freeform Fabrication (EBF3) technology along the way. She spent 3 hours in zero-gravity (in 15-second increments!) while parabolic flight testing EBF3 for compatibility with the space environment. Karen earned the NASA Exceptional Achievement Medal in 2007, the NASA Exceptional Technology Achievement Medal in 2014, and her team received Langley’s Whitcomb-Holloway Technology Transfer Award in 2008 and runner-up for NASA Patent of the Year in 2016. Karen earned her BS in 1989 and MS in 1999 both in Materials Engineering from Virginia Tech.

2023 BIG Idea Challenge Co-Chair


Kevin Kempton currently works with the Center of Excellence for Collaborative Innovation (CoECI) team and provides technical support for many crowdsourcing projects. He also supports the Game Changing Development Program as a Program Element Manager supporting technology development projects. While supporting CoECI and GCD, Kevin recently led several concept studies such as the Mars Ice Home habitat, the Advanced Lightweight Lunar Gantry for Operations (ALLGO), and the Lunar Torch mobile lunar heliostat. Mr. Kempton was also the PI for a NASA Innovative Advanced Concepts (NIAC) Program study called PHLOTE (Phobos L1 Operational Tether Experiment).

Previously, Mr. Kempton was the project manager for the Autonomous Landing and Hazard Avoidance Technology (ALHAT) Sensor Development at Langley where he planned and supported the integration and flight test campaigns that led up to the successful flight test of the ALHAT system on the Morpheus vehicle at KSC. Before ALHAT, Mr. Kempton was the Lead Systems Engineer for the CLARREO Climate Mission Development. He also served as the Lead Systems Engineer and Verification Manager for the Ares I-X Demonstration Flight Test and was awarded the NASA Exceptional Achievement Award as well as the Space Flight Awareness Award for leadership and innovations in systems engineering.

Robert Carter
Robert Carter
NASA Glenn Research Center


Robert Carter is Deputy Chief of the Materials and Structures Division at the NASA Glenn Research Center (GRC). The Division’s 10 branches, and workforce of approximately 250 civil servants and contractors, field a wide range of research and engineering efforts in materials, structures, and mechanisms for extreme aerospace environments. This work spans all technology levels from fundamental atomistic modeling for discovery of new materials, to full-scale structural testing and qualification of flight hardware. He previously served as Chief of GRC’s High Temperature and Smart Alloys Branch, where he oversaw a diverse research and development portfolio and championed revitalization of GRC’s alloy processing capabilities, with special emphasis on establishing a core competency in production of custom alloy feedstocks for additive manufacturing.

Mr. Carter began his career at the NASA Marshall Space Flight Center where he was the Element Discipline Lead Engineer for Production of the Space Launch System (SLS) Core Stage, was Team Lead for Welding and Manufacturing, and was one of the early pioneers in the research and development of Friction Stir Welding for space flight hardware. He holds a Master’s degree in Materials Engineering from Auburn University and a Bachelor of Science degree in Welding Engineering from The Ohio State University.

Bill Frazier
Dr. Bill Frazier
Pilgrim Consulting


Dr. Bill Frazier received his BS, MS, and Ph.D. degrees in Materials Engineering from Drexel University. He is a graduated the Naval Aviation Executive Institute's Senior Executive Management Development Program, and the Defense Systems Management College's Advanced Program Management Curriculum.

Dr. Frazier founded Pilgrim Consulting LLC following a successful 39 year long career within the Department of the Navy. Upon retiring, he held the positions of “The Navy Senior Scientist for Materials Engineering,” and “The Chief Scientist for the Air Vehicle Department” at the Naval Air Systems Command (NAVAIR).

Dr. Frazier is a recognized expert in (i) materials qualification and certification, (ii) manufacturing and processing, (iii) additive manufacturing (AM), and (iv) strategic planning. He was the technical architect of NAVAIR’s strategic efforts to deploy additive manufacturing technology in order to enhance operational readiness and reduce sustainment cost. Dr. Frazier led the technical effort culminating in the certification and flying the Navy’s first flight critical AM component, viz., the V22 Osprey engine nacelle link.
