AVO Staff Directory

AVO is a very extended family. Some people work full time for the observatory, others well under half time. Others perform essential work, but only draw operating expenses. Several agencies contribute personnel at several locations. A wide variety of disciplines are represented, including geophysics, geology, glaciology, hydrology, geochemistry, remote sensing, computing, electronics, and administration. The following people are the paid staff, and share among themselves about 22 Full Time Equivalent positions.
