Daniel Allen

Graduate Research Assistant

My name is Daniel Allen. I grew up in Seymour, TN as an avid hillbilly and spent most of my free time exploring the Great Smoky Mountains National Park by camping, hiking, and swimming. My hobbies include extensively adventuring anywhere I end up and seeing how many flips I can do after leaping off cliffs into water. I graduated from the University of Tennessee at Knoxville in 2020 with a Bachelor’s of Science in Aerospace Engineering. In my time at UTK I was the Treasurer of the Gymnastics Club for three years. I am pursuing my Master’s degree in Aerospace Engineering.

James Chism

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 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 is working on fluid-structure interactions for high-speed flows, with an emphasis on shock-boundary layer interactions. James is pursuing a Ph.D. degree and is being supervised by Dr. Phil Kreth.

Jack Cobourn

Graduate Research Assistant

Jack Cobourn was raised in Phoenix, AZ, and graduated from Lafayette College with a Bachelor’s of Science in Mechanical Engineering and a Bachelor’s of Art in Russian and Eastern European Studies. His honors thesis involved the design and construction of a high-speed laser florescence imaging system for use with a Mach 4 expansion tube. 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.

Autumn Douthitt

Graduate Research Assistant

Autumn was born and raised in Clarksville, TN and graduated from Montgomery Central High School in 2013. She also completed her English and Calculus I and II credits at Austin Peay State University through a dual enrollment program before college. Autumn has recently graduated in May 2017 from Tennessee Technological University in Cookeville, TN with a B.S. in Chemical Engineering with a Bio-molecular concentration. On campus, she was actively involved with the American Institute of Chemical Engineers (AIChE) and the TTU chapter of the Society of Women Engineers (SWE). She performed research all four years at Tennessee Tech and achieved Distinction in the Major after composing a mini-thesis and presenting her research pertaining to modeling electric field distributions of dividing cancer cells. Autumn has also participated in three NSF-funded Research Experience for Undergraduates (REU) summer programs before graduating, which has provided her with a broad research background. Her research with the HORIZON group at UTSI focuses on Fast-response Pressure Sensitive Paint.

Haley Goldston

Graduate Research Assistant

Haley is an Air Force brat born in Lakenheath, England. She grew up in Biloxi, Mississippi and graduated high school in Harriman, Tennessee. Haley earned her Bachelors degree in Mechanical Engineering from Tennessee Tech University. Her extracurricular activities included serving as President of the Student Veterans Organization and Outreach Coordinator for the Society of Women Engineers. Haley’s mother and father are public school teachers and she has one older brother who serves in the Air Force. Here at UTSI, Haley is pursuing a Masters degree in Aerospace Engineering with a concentration in Thermal-Fluid Mechanics. She will begin her research for Horizon group in Spring 2020 under Dr. John Schmisseur.

Kyle Klingaman

Graduate Research Assistant

Kyle Klingaman was raised in Lakewood, New Jersey and graduated from Middle Tennessee State University in 2019 with a degree in Aerospace Technology and a minor in Mathematics. He will be attending the University of Tennessee Space Institute in Fall 2020 to pursue his Master’s degree in Aerospace Engineering.

Lauren Lester

Graduate Research Assistant

Lauren Lester was raised in Millington, TN and graduated from the University of Tennessee, Knoxville in December 2018 with a Bachelor’s of Science in Mechanical Engineering. On campus, she served on the WomEngineering Leadership Council as a student representative for the Department of Mechanical, Aerospace, and Biomedical Engineering and was the president of the AIAA Knoxville chapter. She previously worked as an intern with the Horizon Research Group during the summer of 2017, creating an axisymmetric test model for the Mach 2 wind tunnel. She is now a Ph.D. student working under Dr. Phil Kreth.

Stefen Lindörfer

Graduate Student

Stefen Lindorfer graduated from Purdue University in May 2014 with a Bachelor of Science in Aeronautical and Astronautical Engineering, and from UTSI in May 2017 with a Master of Science in Aerospace Engineering. Stefen is currently pursuing a PhD in Aerospace Engineering while working at the Arnold Engineering Development Complex. His research interests are applied aerothermodynamics by computational methods with a focus on flow quality for wind tunnels and shock-wave/boundary layer interactions.

Mason Pohlman

Graduate Research Assistant

Mason Pohlman was born and raised in Jacksonville, Illinois. He graduated from Belmont University in Nashville, Tennessee with a B.S. in Engineering Physics and Honors. His Honors Thesis at Belmont centered on the debate between science and religion. He enjoys hiking, fishing, painting, and everything sports. Mason joined the HORIZON group as a graduate research assistant in 2020 and is looking to complete a Master’s degree in Mechanical Engineering. He will begin his research in the Fall 2020 under Dr. Schmisseur.

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.

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.
