Gregory Griffin, PhD

Member of Technical Staff


Greg Griffin is a Technologist in the Computer Vision Group. Between 1990 and 2005 he worked in the field of astrophysics analyzing cosmic microwave background anisotropies and observing from the South Pole in Antarctica. After working on the BICEP experiment in 2004-2005, he went back to school and received his Ph.D. in Computation and Neural Systems from Caltech in 2013. Over the last decade he has worked on visual classification, specifically: machine learning methods for automatically organizing visual information into hierarchies for fast detection. His more recent work includes investigating wide-baseline stereo imaging and its applications.
