Dr. Frank Soltis created the revolutionary computer architecture used in today's IBM iSeries. Based on his Ph.D. dissertation research, his architecture first appeared in the IBM System 38 and later in the IBM AS/400. The technology-independent machine interface and the single-level addressability that he originally proposed have led to a totally new breed of computers. Dr. Soltis is a frequent speaker at many computer conferences around the world, and he is an award-winning author with several publications to his credit, including his best-selling book, Inside the AS/400. His "By Design" column is a regular feature in News/400 magazine. His latest book is Fortress Rochester, The Inside Story of the IBM iSeries.

During the last few years he led effort to define the architecture of the 64-bit PowerPC processors used in the IBM iSeries and pSeries servers. As the IBM iSeries Chief Scientist, he continues to define future directions for the iSeries. In addition to his IBM responsibilities, he is an Adjunct Professor in the Department of Electrical and Computer Engineering at the University of Minnesota, where he teaches graduate courses on high-performance computer design.
