2019 Interns

Daniel Allen

Daniel was raised in Seymour, TN. He’s a rising senior studying aerospace engineering at the University of Tennessee, Knoxville. He loves nature and will be the first one to propose any adventure. On campus he is the treasurer of the Gymnastics Club and a member of AIAA. In the HORIZON group at UTSI, he is characterizing the mitigation of laser-induced blast waves using turbulent flow from a Mach 1.5 jet.

Harold LaCroix

Harold LaCroix was born and raised in Thompsons Station, Tennessee, where he graduated from Independence High School in 2017. He is currently a junior at the University of Alabama, Huntsville where he is pursuing a bachelor’s degree in aerospace engineering. His main interests are rocketry and rocket propulsion. Outside of his schoolwork, he competes on his school’s cross country and track and field teams. With HORIZON, he is working on testing the effects of turbulence on shock waves.

Shelby Ledbetter

Shelby Ledbetter was raised in Bristol, Tennessee where she graduated from Tennessee High School in 2018. She is a rising sophomore at the University of Tennessee, Knoxville studying aerospace engineering. On campus she is a member of AIAA, Society of Women Engineers, Habitat for Humanity, and the ENGAGE Engineering Leadership Team. With the HORIZON research group, she ran an oil flow campaign on a sharp fin in the Mach 2 wind tunnel and assisted with schlieren and shadowgraph in Mach 2.

Zach McDaniel

Zachary McDaniel was in raised in Greenwood, Indiana and is currently a junior pursuing a bachelor’s degree in aerospace engineering at Purdue University. He is involved in the Society of Engineering Development and Students for the Exploration and Development of Space at Purdue. With the HORIZON Research Group, he worked to create shock tracking software for cylinder-induced shock-wave/transitional boundary-layer interactions. His main interests include computational and experimental fluid dynamics, data science, and aerospace applications of machine learning. Outside of school work, Zachary enjoys learning about politics, watching movies, and playing wallyball.
