Alex Iaccetta won a 2014 NASA Space Technology Research Fellowship (NSTRF14), for his proposal titled "Astro-Interferometric Modeling and Spatio-Spectral Reconstruction."
Matt Bergkoetter won the Synopsis 2013 Robert S. Hilbert Memorial Optical Design Competition. His project, "Extended Depth of Field in an Intrinsically Wavefront-Encoded Biometric Iris Camera" earned him a $1,000.00 prize. He is the fourth student in our group to win this prize, along with Matt Bolcar, Manuel Guizar-Sicairos and Dustin Moore.
Dustin Moore won the best student presentation award for a paper, "Wavefront Sensing by Phase and Modal Amplitude Retrieval," he gave at the Adaptive Optics topical meeting of the Optical Society of America in Arlington, VA, June 25, 2013.
Matt Bergkoetter, Alden Jurling and Dustin Moore were all selected as recipients of an NSF Travel Grants, paying for their travel expenses to the Imaging and Applied Optics Congress of the Optical Society of America.
Prof. Fienup won the OSA's Emmett Leith Medal and was elected to the National Academy of Engineering.
