Nehorai LabPreston M. Green Department of Electrical and Systems Engineering Center for Sensor Signal
and Information Processing
Overview
Dr. Nehorai graduated 32 Ph.D. studentsof whom, 11 are faculty members, 3 are ingovernment research labs, and 17 in industry(including 4 in finances, and 2 in start-ups).Recent employers include Google, Facebook,Oracle, Walmart Labs, and Exploratory start-up.
Research themes: We develop models ofcomplex systems, use statistical signal processing,machine learning, imaging, and optimizationto analyze data and solve important societalproblems.
