Research Overview

Research is currently conducted in six areas: alignment coatings and mechanisms of alignment for liquid crystal devices; pH adjustment in magnetorheological fluids for acid polishing of polycrystalline ceramics; anisotropic optical effects for the manipulation of polarization of large, high peak power lasers; nanomechanical properties of fragile, metal-oxide structures used in the manipulation of light; properties of multilayer, dielectric thin film coated optics in adverse chemical environments; effect of environment on laser induced damage in optical materials. Extensive laboratory facilities are available within our research group for undergraduate interns, co-op students and graduate students to carry out experiments (see facilities list on our website)
