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."
