D. Jeffs received B.S. and M.S. degrees in electrical engineering from Brigham Young University in 1978 and 1982 respectively. He received the Ph.D. degree from the University of Southern California in 1989, also in electrical engineering. Since 1990 he has been on the faculty of the Department of Electrical and Computer Engineering at Brigham Young University and currently holds the rank of professor. He lectures in the areas of digital signal processing, signals and systems, and detection and estimation theory.

Previous employment includes Hughes Aircraft Company where he served as a sonar signal processing systems engineer in the anti-submarine warfare group. Projects there included algorithm development and system design for digital sonars in torpedo, surface ship towed array, and helicopter dipping array platforms.

Research interests include digital array signal processing for radio astronomy and multiple antenna wireless communications. He co-directs the Radio Astronomy Systems research group at BYU which is actively developing astronomical instrumentation and signal processing algorithms. Dr. Jeffs is currently principal investigator for a National Science Foundation grant of $5.8M to develop a phased array feed beamforming instrument for the Arecibo Radio Telescope in Puerto Rico. This system will dramatically increase the sky survey speed of one of the most sensitive telescopes in the world.

Dr. Jeffs served year-long sabbatical leaves at Delft University of Technology, The Netherlands (2004-05), and Australia Telescope national Facility in Sydney (2013-14). In The Netherlands he collaborated with ASTRON in developing and analyzing techniques for self-calibration of the LOFAR low frequency radio astronomy array, and in Australia he worked on radio interference cancelation methods for the ASKAP radio telescope array.

Dr. Jeffs was a Vice General Chair for IEEE ICASSP-2001, held in Salt Lake City Utah. He was a member of the executive organizing committee for the 1998 and 2015 IEEE DSP Workshops, and on the scientific organizing committees for several years of the Calibration and Imaging Workshop (CALIM), RFI Workshshops, and Phased Array Antenna Systems for Radio Astronomy Workshop. He served several years as chair of the Utah Chapter of the IEEE Communications and Signal Processing Societies.
