Bradford Chamberlain is a Principal Engineer at Cray Inc. where he works on parallel programming models, focusing primarily on the design and implementation of the Chapel language in his role as technical lead for that project. Brad received his Ph.D. in Computer Science & Engineering from the University of Washington in 2001 where his work focused on the design and implementation of the ZPL parallel array language. In the past, he has also worked on languages for embedded reconfigurable processors and on algorithms for accelerating the rendering of complex 3D scenes. Brad remains associated with the University of Washington as an affiliate faculty member and is currently teaching a Professional Masters course on Parallel Computation. He received his Bachelor's degree in Computer Science with honors from Stanford University in 1992.

Sung-Eun Choi is currently a member of the Chapel group at Cray, Inc. in Seattle, WA. Before joining the Chapel group, she was the lead runtime developer for the Cray XTM (TM) system, a full-custom massively multithreaded computer system. Prior to that, she worked on scalable system software in the Advanced Computing Laboratory at Los Alamos National Laboratory. Sung-Eun holds a Ph.D. in Computer Science from the University of Washington in Seattle.
