Interest Areas

Dr. Roberts specializes in theoretical and experimental wave propagation in acoustic and elastic media and methods for data inversion. His theoretical work addresses development of efficient computational methods for forward-modeling of wave propagation and scattering phenomena, and the use of computational methods for the inversion of scattering data. This latter area also includes work in limited data X-ray computed tomography. He has experimental expertise in ultrasonics as applied to nondestructive evaluation and bio-technical applications.
