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.

Kristi manages The USGS/AVO Alaska Tephra Laboratory (ATL) and Data Center. The ATL is an interdisciplinary center for the study of tephra fall (volcanic ash) erupted from Alaskan volcanoes and serves as a regional facility for the storage and management of tephra data. The ATL houses data and physical archives including a growing reference collection for the USGS/AVO and its collaborators.

Kristi's research focus includes tephrochronology, tephrostratigraphy, and ashfall impacts.
