Attention U. Rochester Grad Students

Opportunity to join an exciting group
Performing research on Imaging Science

with Dr. James R. Fienup, the Robert E. Hopkins Professor of Optics at the University of Rochester’s Institute of Optics

Primary current areas of interest include:
Wavefront sensing for adaptive optics by phase retrieval / phase diversity:
Phasing the segmented primary mirror for the James Webb Space Telescope
Optical metrology using phase retrieval
Digital holography for imaging through atmospheric turbulence
Large ground-based or space telescopes using sparse apertures or segmented optics
Understanding image quality, effect of aberrations
Image restoration/reconstruction algorithms
Unconventional imaging systems, for example: laser illumination with no image-formation optics, imaging through atmospheric turbulence, super-resolution by structured illumination
Phase retrieval algorithms for image reconstruction (e.g., from X-ray diffraction data)

Also interested in:
Image reconstruction for medical imaging modalities (e.g., microscopy, ultrasound, MRI), Synthetic-Aperture Radar

Research involves theoretical analysis, computer simulation, algorithm development, optical laboratory experiments.

You will enjoy this research group if you like mathematics and signal processing, image reconstruction algorithms, laboratory proof-of-principle experiments, and solving difficult, important problems. There is a great job market for researchers with expertise in imaging science.
