B.S. in Aerospace Engineering (2021) – Texas A&M University

Kevin is a Ph.D. candidate in the Department of Aerospace Engineering at Texas A&M University. As an undergraduate, Kevin was a National Merit scholar and was supported by the Texas A&M University President’s Endowed Scholarship and graduated with a Bachelor of Science in Aerospace Engineering and a minor in Mathematics in December 2021. Throughout his tenure at Texas A&M, he has completed internships with ATA Engineering, Inc., the Air Force Research Laboratory Directed Energy Directorate, and L3Harris Technologies.

Kevin’s current research seeks to reduce the acoustic emissions of cavities in flow through hybrid structural morphing, a technique which simultaneously applies large, quasi-static deformations and small, high-frequency vibrations to aerodynamic surfaces. This work is supported by the NDSEG Fellowship Program and includes time-resolved simulation of turbulent flows on Texas A&M and DoD high-performance computing systems, structural design, vibration analysis, and aeroacoustic wind tunnel testing. His previous work developing a high-resolution continuous-scan (CS) acoustic imaging system and mathematical methods for high-speed processing of CS acoustic data is critical in this effort, providing improved source separation and spatial filtering for high-background acoustic testing. Additional previous research has studied superelastic slat cove and gap fillers intended to reduce high-lift device noise on commercial air transports, the automated identification and classification of atmospheric turbulence using sonic anemometry, and the development of shape memory alloy-actuated flow control devices.
