Computational sensing with a focus on novel, physics-based measurement techniques for practical applications. Primarily focused in the electromagnetic/optical spectrum ranging from ELF through visible and hard X-rays, with applications to security, non-destructive testing, and medical imaging. Investigations range from basic science (e.g. fundamental studies in material science, optics, and information science) to applied and transitional work (e.g. design and implementation of architectures at the system level targeted at particular, real-world problems)
