Researcher (1993-present)
Dr. Koenig was a major contributor to the successful "720 Redesign." Since being hired by Kappa's Skunk Works, she has applied for, and been granted, nine patents, including the patents for the pretzel, rhizome, and corkscrew transformations (the former two shared with Dr. Chiang).

Selected Experience
Between 1988 and 1993, Dr. Koenig served as a Senior Scientist with Raytheon Corporation. Prior to that, she worked in the research laboratories of International Business Machines (IBM) Corporation from 1979-1998. During that period she was also alLecturer in Mathematics at the State University of New York, Binghamton NY.
