William A. Bristow
Professor of Electrical Engineering
Biographical Sketch:
Present Research Interests:
Dr. William Bristow's current research interests include included studies of winds in the upper atmosphere, studies of the magnetosphere-ionosphere coupling, and space-weather effects on radio propagation, which directly impacts radio communications in high-latitude regions. Dr. Bristow is the principle investigator for the SuperDARN network which consists of two radar systems in Alaska.
