Heltzel received BSME and MSME from the University of Dayton in 2002 and 2003 respectively, and a PhD from the University of Texas at Austin in 2006.  He is currently a Senior Engineer for PCKA. Dr. Heltzel is the principal investigator on NASA and Air Force projects involving emerging technologies in aerospace thermal management.  He also conducts research in the field of micro/nanoscale energy transport.  Prior to joining PCKA, he performed computational research at the Air Force Research Laboratory in support of low temperature jet fuel stability.  He has acted as a consultant to technology startup companies, and authored a book chapter on laser materials processing.  Dr. Heltzel has published several papers in the area of near-field optics and plasmonics, and was awarded the 2006 American Institute of Aeronautics and Astronautics (AIAA) Best Paper in Thermophysics for work on surface plasmon-based nanolithography.
