Biosketch:

A native of Wyoming, Dr. Green has been a faculty member at NDSU since 1998. In addition to his professional interests, Dr. Green enjoys spending time with his wife and two children, reading, backpacking, archaeology, Native American studies, cross-country skiing, archery, and fly-fishing.

Academic Career:

Dr. Green obtained his Ph.D. in Electrical Engineering from the University of Wyoming in July of 1998 after completing his dissertation, entitled "Space-Time Evolutionary Fourier Analysis". At the same time, he obtained a graduate minor in statistics. Prior to his Ph.D. work, Dr. Green earned M.S. and B.S. degrees in Electrical Engineering from the University of Wyoming in 1994 and 1992, respectively.

Research Interests:

Currently, Dr. Green’s professional research interests focus on digital and statistical signal processing, time series analysis, spectral and time-frequency analysis, array processing, real-time systems, and data adaptive techniques. In the fall of 2004, Dr. Green established the Digital Signal Processing (DSP) scholar-team. This team, comprised of both undergraduate and graduate students, has engaged in a variety of hands-on DSP activities including the design, fabrication, and implementation of a custom DSP board for audio processing applications.

Professional Activities and Service:

Dr. Green is a long-time and active member of the Institute for Electrical and Electronics Engineers (IEEE) as well as the American Society of Engineering Educators (ASEE). Dr. Green is a regular reviewer for the National Science Foundation, particularly for the Small Business Innovation Research (SBIR) program and the Biomedical Engineering Research to Aid the Disabled (BRAD) program. Each year, Dr. Green also reviews conference papers, journal papers, and books for a variety of organizations.

Awards and Honors:

While at the University of Wyoming, Dr. Green was one of seven U.S. participants selected for the Monbusho research Experience Fellowship for Young Foreign Researchers; he studied at the National Astronomical Observatory in Mitaka City, Japan, during the summer of 1995.
