Biography:

John Treichler received his BAEE and MEE degrees in 1970 from Rice University and his PhD in Electrical Engineering from Stanford University in 1977.

In January 1984, Dr. Treichler co-founded Applied Signal Technology, Inc., a company that builds signals reconnaissance and intercept equipment for the U.S. Government and its allies. Under his technical leadership, the Company has grown to more than 700 employees and is one of the world’s leaders in the application of signal processing technology to national defense needs.

During the 1983-84 academic year, Dr. Treichler was an Associate Professor in the School of Electrical Engineering at Cornell University, where he taught both graduate and undergraduate courses and performed research in the area of communications and adaptive filtering.

From 1977 to 1983, Dr. Treichler worked at ARGOSystems, Inc. on a variety of projects aimed at applying advanced signal processing theory and hardware concepts to applications of interest to the U.S. Government. Among these projects were the development of the first digital subband tuner, the development of new algorithms for removing multipath and interference from FDM/FM and PCM signals, and the development of transmultiplexer-based signal sorting systems. He was involved in the projects at many levels, including task and project leader, program manager, and system engineer. As Senior Scientist of the Strategic Systems Division he directed a wide range of technical, marketing, and IR&D initiatives.

During 1974 to 1977 Dr. Treichler worked on sonar and radar signal processing in the Information Systems Laboratory at Stanford University. This work led to the characterization of the Adaptive Line Enhancer, which was published in his doctoral dissertation, The Spectral Line Enhancer: The Concept, An Implementation, and An Application.

From 1970 to 1974 Dr. Treichler was a line officer in the U.S. Navy, serving in the Operations Department aboard two destroyers in the Atlantic Fleet and attaining the rank of Lieutenant.

Dr. Treichler has written or co-authored more than a dozen refereed articles for technical journals and many papers for technical conferences and workshops. He has co-authored a book entitled Theory and Design of Adaptive Filters, and has recently completed, along with several coauthors, a text for high school students entitled Engineering: Our Digital Future.
