At Lafayette, he served as president of the college’s chapter of The American Society of Mechanical Engineers. Here at Horizon, Jack will pursue his Master of Science in Aerospace Engineering, conducting research on characterizing the Mach 4 tunnel and expanding current optical flow diagnostic capabilities.

James Chism

Graduate Research Assistant

James Chism was raised in Hickory Withe, Tennessee and graduated from Mississippi State University in 2018 with a degree in Aerospace Engineering and a minor in German. He will be attending the University of Tennessee Space Institute in the fall to pursue his Master’s degree. He is an avid outdoorsman who enjoys hiking, fishing, and hunting. His research at Mississippi State focused on long range ballistic trajectories and subsonic bullet applications in wildlife management. With Horizon, he will be working on particle tracking in high speed imaging as well as assisting in high speed experimentation in wind tunnels.

Kate Stamper

Graduate Research Assistant

Kate Stamper was raised in Ooltewah, TN and graduated from the University of Tennessee Knoxville in 2017 with a degree in Aerospace Engineering through the Chancellor’s Honors Program. Her senior design project focused on developing a deep space mission using three separate spacecraft to reach three trans-Neptunian object systems with the use of a single launch vehicle and will be presented at the AIAA Astrodynamics Specialist Conference in August. This summer, with the HORIZON group, she will be spearheading the redesign of the Mach 2 tunnel test section. She will be pursuing her Master’s Degree in Aerospace Engineering at the University of Tennessee Space Institute in the fall working with the HORIZON group.

Kevin Holst

Graduate Student

Kevin received his B.S. in Aerospace Engineering from the University of Tennessee at Knoxville in 2007 and his M.S. in Aerospace Engineering from the University of Tennessee Space Institute in 2012. He has been working at Arnold Engineering Development Complex since the summer of 2007, and currently works in the area of high speed air-breathing propulsion.

Lara Lash

Graduate Research Assistant

Lara Lash was raised in Northern Virginia and obtained her Bachelors of Science in Mechanical Engineering from Lafayette College in 2013. She completed her Master’s in Aerospace Engineering in May 2015 on a trajectory analysis comparing a conventional bell nozzle to an aerospike nozzle for single-stage to orbit flight. She has previously conducted research that involved space environment simulation and combustion instability. Currently, she is working to characterize the unsteady dynamics of transitional shock wave-boundary layer interactions generated by a cylinder on a flat plate as part of her dissertation research. This work is sponsored by the Office of Naval Research.

Matthew Schwartz

Graduate Research Assistant

Matthew Schwartz was raised in Nashville, TN, and graduated from The University of Tennessee Knoxville with an Aerospace Engineering degree in May 2017. He will be attending the University of Tennessee Space Institute in the fall to pursue his Master’s Degree. He was a member of the VolatomiX breakdance team, snowboard club, and an officer of the AIAA Knoxville chapter. This summer at HORIZON, he worked on test cases using US3D and assisted with various other CFD and MATLAB projects. Matthew will be beginning graduate school at UTSI in the fall of 2017.

Nicole Nutter

Graduate Research Assistant

Nicole Nutter was raised in Oak Ridge, Tennessee and graduated from the University of Tennessee, Knoxville in May 2017 with a degree in Aerospace Engineering. Previously, she has conducted numerical studies of scramjet combustion and instability during an internship at the Oak Ridge National Laboratory. Currently, she is a Graduate Research Assistant at UTSI pursuing a Doctor of Philosophy in Aerospace Engineering, and her research work primarily focuses on trajectory analysis of hypersonic vehicles by computational means.

Stefen Lindörfer

Graduate Research Assistant

Stefen Lindorfer graduated from Purdue University in May 2014 with a Bachelor of Science in Aeronautical and Astronautical Engineering, and from the University of Tennessee Space Institute in May 2017 with a Master of Science in Aerospace Engineering. Stefen is currently a Graduate Research Assistant at UTSI, pursuing a Doctor of Philosophy in Aerospace Engineering. His research interests are applied aerodynamics by computational means. He has performed numerical design advancements and a flow quality investigation on a Mach 4 Ludwieg Tube, which will be operational by the summer of 2017. As part of his Master’s thesis, Stefen studied shock wave/boundary layer interactions (SWBLIs or SBLIs) on a standing cylinder by means of CFD, in collaboration with the experimental research performed by the Horizon group. His doctoral research is an extension of this work, focusing on the effects of the ratio of cylinder diameter to boundary layer thickness, both on and off the centerline.

Stu Steen

Graduate Student

Stu was born & raised in Northern Virginia and received his B.S. in Aerospace Engineering from UVa in the spring of 2013. His current research is in laminar-turbulent transition, and is working on the computational design of a planar hypersonic quiet nozzle. He currently works at the Arnold Engineering Development Complex as a CFD analyst.

Theron Price

Graduate Research Assistant

Theron Price graduated from the University of Tennessee, Knoxville in May 2015 with a Bachelor of Science in Aerospace Engineering. He further obtained a Master of Science in Aerospace Engineering with a thesis comprising experimental research into acoustic propagation through nozzles of dissimilar convergent contours and how this pertained to the topic of combustion instability for conventional propulsion. Presently, Theron is continuing his studies as a Graduate Research Assistant at UTSI, with the intent of achieving a Doctor of Philosophy in Aerospace Engineering. His research interests primarily fall under the broad domain of combustion instability, and tend toward the study of the acoustics involved. Additional subjects of interest involve acoustics in general, celestial mechanics and space flight, and the analysis of nonlinear systems. Theron intends to continue experimental research into aeroacoustics as it relates to propulsion as a student under Dr. Phil Kreth.
