James D. McCaffrey is an American research software engineer at Microsoft Research known for his contributions to machine learning, combinatorics, and software test automation.

Education

McCaffrey earned a BA in experimental psychology from the University of California, Irvine, a B.A. in applied mathematics from California State University, Fullerton, an M.S. in computer science information systems from Hawaii Pacific University, and a Ph.D. in interdisciplinary computational statistics and cognitive psychology from the University of Southern California.^[1]

Career

Prior to joining Microsoft, McCaffrey was the Associate Vice President of Research at Volt Information Sciences in Redmond, Washington, supporting the needs of software engineers at Microsoft. He joined Microsoft as a software engineer in 2006 and worked on various Microsoft products, including Exchange Server, Azure, and Bing. He then became a research software engineer at Microsoft Research, where he directs the internal Microsoft AI School, focusing on creating machine learning and artificial intelligence algorithms. He is the Senior Technical Editor for Microsoft's Visual Studio Magazine.^[1]

His research at Microsoft primarily focuses on machine learning. His other research interests include combinatorics, especially when applied to human behavior such as sports betting and Blackjack Switch, as well as "software systems which have designs influenced by the behavior of biological systems such as swarm intelligence optimization and simulated bee colony algorithms and their application to data mining.^[1]
