Ryan Alimo is a machine learning scientist and intrapreneur at the Jet Propulsion Laboratory, California Institute of Technology's Deep Learning Group. Ryan Alimo's research interests span theory and practice of black-box optimization for machine learning. In particular, he has been working on the development and analysis of machine learning algorithms for teams of spacecraft, which can cooperate to form virtual structures such as synthetic apertures radar (SAR), and can perform distributed measurements that is usually not possible with a single spacecraft.
