Micropaleontology, of siliceous microfossils, including radiolarians and diatoms. Current research projects: the use of Paleozoic radiolarian biostratigraphy to resolve structural and stratigraphic complexities, use of geochemical proxies to understand Paleozoic radiolarian paleoecology, freshwater diatom paleoecology, analysis of Tertiary and Quaternary diatomites in the Great Basin, and Columbia River Plateau. K-12 outreach in general paleontology and earth science.
Relevant Past Experience:
Micropaleontological consultant providing biostratigraphic dating of radiolarians for the mining industry and government agencies. Over 15 years experience working on Paleozoic basinal rocks in Nevada, particularly the Roberts Mountains allochthon. Other field projects in the Delaware Basin and Ouachita orogenic belt in west Texas, Silurian of the Canadian arctic, Carboniferous of Turkey, and Ordovician of the Lachlan fold belt, Australia. Some work with diatomite deposits in association with the industrial minerals industry. Active member of the International Association of Radiolarian Paleontologists, Geological Society of America, past president of West coast section of the Paleontological Society.
