Ryan Michael Rifkin, an American mathematician and computer scientist with expertise in machine learning, affiliated with Google Inc., Mountain View, California and previously at Honda Research Institute, Boston, and the MIT Center for Biological and Computational Learning. He holds a Ph.D. from MIT on machine learning in 2002. In the early 90s, along with primary author Bradley Kuszmaul, Ryan Rifkin co-authored the massive parallel chess program StarTech which competed the ACM 1993 running on a CM-5. He optimized some move generation routines in assembly language, and cleaned up the parallel work-stealing code.

=Quotes= from Bradley Kuszmaul's Ph.D. thesis The code for move generation and checking illegal moves, which takes a total of 3.5% of the cycles, was optimized in assembly language by Ryan Rifkin under the direction of Mark Bromley of Thinking Machines Corporation. Before Ryan worked on that code, the move generation and illegal move checking accounted for about 9% of all the cycles.
