Dr. John D. Schmisseur
Dr. John D. Schmisseur joined the faculty of the University of Tennessee Knoxville Department of Mechanical, Aerospace, and Biomedical Engineering on August 1, 2014. He teaches and leads research at the University of Tennessee Space Institute.
Prior to joining the faculty, John was the Chief of the Energy, Power & Propulsion Sciences Division and Program Manager for Aerothermodynamics within the Air Force Office of Scientific Research (AFOSR). During his tenure at AFOSR, John initiated and led a national strategic research plan which has guided the research efforts of multiple federal agencies, championed the transition of basic research capabilities that have advanced flagship national hypersonics technology programs and transformed test and evaluation capabilities, and envisioned the HIFiRE program which unifies the efforts of AFRL, NASA and the Australian DSTO to advance fundamental hypersonic science and technology via flight research. He is active within the professional community including having served as Chair of the AIAA Fluid Dynamics Technical Committee and a NATO Science and Technology Organisation working group. Dr. Schmisseur earned his B.S. (90) and M.S. (92) in Aerospace Engineering from the University of Texas at Austin and his Ph.D. (97) in Aeronautics and Astronautics from Purdue University. He is a Fellow of the American Institute of Aeronautics and Astronautics (2012) and the Air Force Research Laboratory (2013) and is the 2008 recipient of the Air Force Science and Engineering Award in Research Management.
Dr. Ryan Bond
Dr. Ryan Bond's research area is Computational Fluid Dynamics (CFD). Dr. Bond's expertise is software and algorithms development for CFD, particularly for high temperature gas dynamics and thermochemistry relevant to hypersonic flows. Prior to joining UTSI, Dr. Bond spent 12 years at Sandia National Laboratories, 7 as R&D staff and 5 as a manager, and 2 years at Arnold Engineering Development Complex (AEDC). Dr. Bond holds bachelor's degrees in Aerospace Engineering and Mathematics from Mississippi State University, a master's and Ph.D. in Aerospace Engineering from North Carolina State University, and an M.B.A. from the University of New Mexico.
Dr. Christopher Combs
Dr. Christopher Combs received his B.S. in Mechanical Engineering from the University of Evansville in Evansville, IN in 2010 and completed his Ph.D. in Aerospace Engineering at The University of Texas at Austin in 2015. His primary area of research interest is laser diagnostics applied to supersonic flows and his research in the application of PLIF to characterize low-temperature ablation was supported through NASA’s Space Technology Research Fellowship program. Dr. Combs joined the faculty at UTSI for the Fall Semester of 2015 and has been leading the development of diagnostic capabilities within the UTSI HORIZON group. Dr. Combs’ is currently a member of the AIAA Aerodynamic Measurement Technology Technical Committee as well as the American Physical Society.
Dr. Phil Kreth
Dr. Phil Kreth received his Ph.D. and B.S. in Mechanical Engineering from Florida State University (FSU) in 2015 and 2008, respectively. Prior to joining the faculty of UTSI in early 2016, he was an adjunct assistant professor and post-doctoral research associate at FSU in the fall of 2015. His expertise is in active flow control and optical diagnostics of high-speed flows. Dr. Kreth is overseeing the installation and commissioning of a new 24” × 24” Mach 4 Ludwieg Tube at UTSI (to be completed in Fall 2017). Additionally, he has been developing high-powered LEDs for use in time-resolved Schlieren/shadowgraph systems (~1 MHz repetition rates), and he is leading the development of fast-response PSP (pressure sensitive paint) techniques. Dr. Kreth is a member of the American Institute of Aeronautics and Astronautics and the American Physical Society.
Dr. Christopher McKenna
Post Doctoral Researcher
Dr. Christopher McKenna received his B.S. in Mechanical Engineering from Lafayette College in 2012 and successfully defended his Ph.D. in Mechanical Engineering in 2017 at Lehigh University. During his undergraduate and graduate educations Dr. McKenna utilized both qualitative and quantitative techniques, such as dye injection, PIV, and LDV, to investigate hairpin vortices, trailing vortices, and vortex impingement. In the fall of 2017 he joined the faculty at UTSI as a post-doctorate contracted to the AFRL on the Arnold Air Force Base. Since his addition to the team Dr. McKenna has been assisting both in the completion of the Mach 4 Ludwieg Tube at UTSI, and in the reactivation of Tunnel D on the Arnold Air Force Base.
