* Tephrochronology, the use of volcanic ash (tephra) layers to provide correlations between sites and age control - including:
-- analytical methods for obtaining geochemical data (e.g. electron microprobe, ICP-OES), including the development of new procedures and new standard reference materials
-- cryptotephra (locating and identifying trace volcanic ash that does not occur as visible layers), especially in glacial ice
-- applications (e.g. Quaternary geology, climate change, paleolimnology, archaeology, paleoseismology)
* Volcanology & petrology, especially of pyroclastic rocks - including:
-- Proximal stratigraphy and geochemistry
-- Eruption and depositional mechanisms (from deposit characteristics such as particle size variations and thickness distributions)* Selected field localities:
-- Newberry Volcano, Oregon
-- Summer Lake and Fossil Lake, Oregon (Great Basin region)
-- central Alaska
-- Mt. St. Helens, Washington
