Biography
Professor Dahl's main research interests are in the area of underwater acoustic remote sensing, acoustic interaction with the sea surface and sea bed, acoustical imaging, and medical ultrasound.His most recent work concerns the application of the van Cittert-Zernike theorem to the understanding how sound interacts with the sea surface. This has important application in underwater acoustic communication and imaging. Prof. Dahl has conducted several ocean-going experiments involving underwater acoustics, the most recent being the Asian Seas International Acoustics Experiment (ASIAEX) sponsored by the U.S. Office of Naval Research. This was conducted in the East China Sea in spring 2001, and involved the U.S., China and Korea; Prof. Dahl was U.S. chief scientist for ASIAEX.
Together with Prof. Reinhall, he has developed a course, Applied Acoustics, emphasizing the learning of acoustics through application. He has also lectured in the University of Washington's Gear-Up Program for high school students, and presented a month-long course, What is Sound?, to freshman as part of the University of Washington's fall early start program.
In 2002 he was a Guest Professor at the University of Bergen Department of Physics. Prof. Dahl is a Fellow of the Acoustical Society of America, a former Associate Editor for the IEEE Journal of Oceanic Engineering, and current national chair of the Underwater Acoustics Technical Committee for the Acoustical Society of America.
