Garrett is an AI Research Scientist at Invitae, applying machine learning to medical genetic testing. He received his PhD in Computer Science at UMass Amherst, advised by Dr. Daniel Sheldon, where he developed algorithms to help scientists in all fields do their jobs more efficiently and effectively, including helping ornithologists and conservationists to study continent-wide bird migration patterns. His thesis was on machine learning for differential privacy. Prior to UMass, he worked at MIT Lincoln Lab. He received an MEng in Computer Science in 2011 and a B.S. In Applied Physics in 2010, both from Cornell University.
