AVO Personnel Directory
AVO is an extended group composed of staff from each of our three partner agencies: the U.S. Geological Survey, the University of Alaska Fairbanks Geophysical Institute, and the State of Alaska Division of Geological & Geophysical Surveys. Some AVO staff work full time for the Observatory but others are with AVO for only a portion of their work hours. A wide variety of disciplines are represented, including geophysics, field engineering, geology, hydrology, geochemistry, remote sensing, informational technology and networking, electronics, and administration.
