Dr. Koo joined the Department of Mechanical Engineering at UT Austin in 2004. He is Senior Research Scientist and Director of Polymer Nanocomposites Technology Lab. He is affiliated with the Advanced Manufacturing Design Center and Texas Materials Institute, Prior to joining UT Austin, he was employed in the aerospace industry for about 20 years by Aerojet, BAE Systems, FMC, and Orbital-ATK. Currently, he is specializing in “Polymer Nanocomposites Technology Designed for Extreme Environments”:

  • Ablation Research
  • Flame Retardant Polymers Research
  • Conductive Polymers Research
  • Polymers for Selective Laser Sintering (SLS) and Fused Deposition Modeling (FDM) in Additive Manufacturing
  • Others

Dr. Koo has an excellent track record for developing well-funded research programs sponsored by AFOSR, AFRL, DOT, DTRA, EPA, FAA, MDA, NASA, NAVSEA, NSF, NSWC, ONR, and other private companies. Dr. Koo has published over 500 publications, presentations, invited lectures, and patents. He is a Fellow of SAMPE and Nanotechnology Committee Chair of SAMPE; and Associate Fellow of AIAA, past chair of AIAA Materials Technical Committee, & Deputy Chair of the Multidisciplinary and Systems Subcommittee of AIAA Emerging Technologies Committee. He is the Editor-in-Chief of Flame Retardancy and Thermal Stability of Materials. He is Associate Editor, International Journal of Energetic Materials and Chemical Propulsion. He serves on the Advisory Board of Carbon Letters, ISRN Mechanical Engineering, and Journal of Nanoparticles.

Dr. Koo has published two books: Fundamentals, Properties, and Applications of Polymer Nanocomposites, Cambridge University Press, Cambridge, UK (2016) and Polymer Nanocomposites: Processing, Characterization, and Applications, McGraw-Hill, New York (2006).
