I have been a consulting geologist for over 25 years, and my teaching focuses on applied field methods for contemporary practice with strategies and advice for entering the professional world.

I am a licensed professional geologist specializing in fluvial and hillslope geomorphology. My work emphasizes projects that focus on flow and sediment management needs to restore geomorphic processes on regulated rivers, including sediment supply and sediment yield analyses; developing sediment management plans designed to help mitigate physical and biological impacts resulting from streamflow and sediment regulation; and developing and implementing monitoring programs to evaluate sediment mobility, transport, and associated geomorphic changes. My professional background also includes engineering geology (hillslope processes, slope stability, fault trenching, drilling, soils sampling and testing) and environmental geology (soil, surface water, and groundwater sampling; contaminant fate and transport analysis).

My research combines field geology, thin section petrography, whole-rock geochemistry, and crystal chemistry to investigate volcanic hazards and better understand what makes volcanoes turn on and off. My favorite kind of research projects blend field work that examines the volume, extent, and manner in which magma was erupted through geologic mapping and stratigraphy, and lab work that characterizes the behaviors and evolution of magma systems through whole-rock geochemistry via x-ray fluorescence and crystal chemistry via electron microscopy. I am also starting to incorporate geochronology techniques like cosmogenic dating of Quaternary volcanic surfaces in my research. My current research projects involving undergraduate and graduate students are based at volcanoes in northern California, like Mount Shasta, the Lassen Volcanic Center, and Medicine Lake Volcano, as well as volcanoes in eastern California, like those near Mono Lake and in the Golden Trout Wilderness of the Sierra Nevada.
