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.
