Previous Research Experience:
As a graduate research assistant at The University of Illinois I was involved in a large collaborative effort with The FAA, NASA Glenn Research Center and The University of Washington to experimentally study the effects of leading-edge ice accretion on the aerodynamic performance of swept wings. I conducted numerous wind tunnel studies in The University of Illinois 3-ft x 4-ft Low Speed Wind Tunnel as well as larger scale studies at the 7-ft x 10-ft Walter H. Beech Wind Tunnel at Wichita State University. One of my primary responsibilities within the overall project was the use of five-hole pressure probe wake surveys to better understand the 3D flowfield and aerodynamics of the swept wing with leading-edge ice. My PhD dissertation was focused on understanding the influence of turbulent velocity fluctuations on the measurements of five-hole pressure probes. I quantified turbulence-induced errors in five-hole pressure probe measurements and developed a method to model and correct these errors.
I have also been involved in several other research projects covering a range of topics such as wake bursting in the flowfield of a multi-element airfoil, the unsteady compressible flowfield of an under-expanded jet and the aerodynamics of splitter plates used for wind tunnel testing of semi-span wings. I have experience with numerous experimental methods including surface oil flow visualization, high-speed Schlieren, thermal anemometers, particle imaging velocimetry, pressure sensitive paint and multi-hole pressure probes.
In addition to my research, I have had a considerable amount of teaching experience, including teaching a senior-level course in aircraft performance and stability, mentoring numerous undergraduates in research and working as an instructor in an aerospace engineering summer camp for high school students.
