He specializes in the implementation of advanced adaptive optics for large astronomical telescopes and other optical systems, including the 6.5 m MMT, and the twin 8.4 m Large Binocular Telescope. His current research tackles tomographic wavefront sensing and deformable mirror development for lightweight imaging systems and high-power beaming systems. Additional work focuses on the development of physically constrained image restoration and video-enhancement algorithms, automatic target recognition, object-independent wavefront sensing, and the recovery of 3-D object structure from blurred imagery.
