Background:

John A. DeSanto received his B.S. (Physics) and M.A. (Mathematics) from Villanova University and his M.S. and Ph.D. (Physics) from the University of Michigan. He held Woodrow Wilson and National Science Foundation Fellowships at the University of Michigan. Before joining the Colorado School of Mines in 1983 he was employed at the Naval Research Laboratory in Washington, D.C., Electromagnetic Applications Incorporated, and the University of Denver. He is a professor in the Department of Mathematical and Computer Sciences.

DeSanto has authored 80 research papers in classical wave theory, most notably sound propagation in the ocean and the scattering of acoustic and electromagnetic waves from rough surfaces. He has edited (Ocean Acoustics), co-edited (Mathematical Methods and Applications of Scattering Theory), and authored (Scalar Wave Theory) books published by Springer, and edited (Proceedings of the Fourth International Conference on Mathematical and Numerical Aspects of Wave Propagation) published by SIAM. He is a Fellow of the Acoustical Society of America and a member of several other technical societies. He wrote the Ocean Acoustics chapter in the Encyclopedia of Physics (3rd Edition, Ed. by R.M.Besancon). He has received several honors and a guest lectureship at Woods Hole. He has recently held Fulbright and National Research Council Fellowships and was Professeur Invite at the Laboratoire d'Optique Electromagnetique, University Aix-Marseille III in 1993.

DeSanto's technical work has been sponsored by the Office of Naval Research, the Naval Research Laboratory, the Naval Underwater Systems Center, the U.S. Army Research Office, and presently, the Air Force Office of Scientific Research for research on electromagnetic scattering from rough surfaces.

DeSanto's theoretical and computational work includes both direct and inverse scattering from rough surfaces. The major focus has been to find the fastest and most reliable computational technique to describe the direct scattering, and to determine the parameter space within which rough surfaces can be reconstructed from data. He is responsible for several research developments in surface scattering, among them the development of combined Feynman diagram and partial summation techniques in spectral space for acoustic, elastic and electromagnetic scattering from rough surfaces, the application of combined physical optics/Fourier expansion techniques for scattering from gratings, the development of mixed coordinate and spectral scattering theories, and highly accurate surface inversion techniques using his spectral-coordinate method. He also is responsible for a method to rigorously relate the solutions of the Helmholtz equation to those of a parabolic equation for waveguide propagation.
