Alexei Maradudin is a Research Professor of Physics at the University of California, Irvine. A condensed matter theorist, his research interests focus on phenomena occurring at surfaces and interfaces. These include studies of linear and nonlinear surface waves of various types, their propagation across rough surfaces, and their scattering by surface and subsurface defects; weak localization effects in the multiple scattering of light from, and its transmission through, randomly rough surfaces; inverse problems in rough surface scattering; and surface photonic crystals. He has published 400 articles devoted to these research areas.
