Zack DeSantis was named a finalist in the Emil Wolf Outstanding Student Paper Competition for his paper “Adaptive Allocation of Measurement Time for Imaging Interferometry” at the Frontiers in Optics (FiO) conference in October 2015 in San Jose, CA.
Scott Paine won third place in the Synopsis 2015 Robert S. Hilbert Memorial Optical Design Competition. His project, "Wide Angle Climbing Camera" earned him a $1,000.00 prize. He is the fifth student in our group to win this prize, along with Matt Bolcar, Manuel Guizar-Sicairos, Dustin Moore, and Matt Bergkoetter.
Alex Iaccetta won a NASA Space Technology Research Fellowship (NSTRF14), for his proposal titled "Astro-Interferometric Modeling and Spatio-Spectral Reconstruction."
