Research Interests

My research interests focus on the mechanics of materials and material behavior. Thus, I have decided to pursue my graduate studies in the mechanical engineering department, while also working with the material science engineering department. My current research focuses on the small-scale examination of deformation mechanisms active in structural materials during very high cycle fatigue. The experiments utilize a novel approach combining portable ultrasonic fatigue at 20 kHz, scanning electron microscopy, electron backscatter diffraction, and optical metrologies for deformation tracking. The use of ultrasonic fatigue enables us to conduct fatigue tests at lifetimes of more than 10^8 cycles in a matter of days, rather than years as required for more conventional methods.
