Vijayaraghava Nalladega is a Research Engineer in the Structural Integrity Division of University of Dayton Research Institute. He has PhD and MS degrees in Mechanical Engineering from University of Dayton, respectively. The primary focus of his research work is materials characterization using atomic force microscopy and scanning probe microscopy techniques. His research also involves the design and development of novel scanning probe microscopy techniques for imaging multiple physical properties of materials at the nanoscale, as well as development of AFM based nanoscale nondestructive evaluation (NDE) techniques. Dr. Nalladega’s other research interests include ultrasonic NDE, nonlinear ultrasonics, and design of interdigital transducer sensors for structural health monitoring (SHM) applications.
