Paul S. Rosenbloom
Paul S. Rosenbloom received his computer science PhD at Carnegie Mellon in 1983. His research includes Soar, which he developed with John Laird, Allen Newell and other collaborators. A 1986 paper studied chunking as a general learning mechanism, and the 1987 Soar paper set out an architecture for general intelligence. He moved to a project leadership role at USC’s Information Sciences Institute in 1987. His later work combined a broad account of computing with Sigma, a cognitive architecture based on graphical models. He became director of cognitive architecture research at USC’s Institute for Creative Technologies in 2014.

Timeline
-
1976–1983
Training and a model of practice
Rosenbloom earned a mathematical sciences degree at Stanford in 1976 and a computer science PhD at Carnegie Mellon in 1983. His dissertation examined chunking of goal hierarchies as a model of practice and stimulus-response compatibility.

1986–1987
Learning inside Soar
With John Laird and Allen Newell, Rosenbloom published work on chunking in Soar in 1986. The three researchers published the general intelligence architecture paper in 1987.

1987–2012
USC and a wider account of computing
He became a project leader at USC’s Information Sciences Institute in 1987. Work on new research directions later informed his 2012 book On Computing, which examined relationships between computing and other scientific fields.

2013–2014
A graphical cognitive architecture
In a January 2013 interview, Rosenbloom described returning to cognitive architecture research with Sigma. Sigma is based on graphical models. He became Director for Cognitive Architecture Research at ICT in 2014.
