My research interests initially focused on fluvial geomorphology, basin-scale geomorphic processes and sediment budgets within forested watersheds. My present research interests involve an integration of late Quaternary tectonic deformation, geomorphic processes, and Quaternary stratigraphy. My projects, which are collaborative efforts with colleagues, use the tools of Quaternary stratigraphic analysis, in conjunction with digital imagery, to decipher paleoseismic history on the Cascadia and Sumatran subduction zones and to better understand tectonic evolution of the Yakima fold province within the Cascadia backarc region of central Washington, USA. While most of my Quaternary stratigraphic investigations have been in coastal wetlands where relative sea level changes inform subduction zone earthquake histories, current investigations of the tectonic geomorphology of the Yakima folds of central Washington state focus more on basin-scale geomorphic processes.
My publications and the thesis topics that I have advised reflect my range of research interests. Field studies have taken me to the northwestern United States (northern California, Oregon and Washington) and Alaska as well as to New Zealand, Japan and Indonesia.
All advised theses are Masters projects with one exception (a Phd thesis in 1999, noted below). Theses prior to 1996 were completed at Western Washington University (WWU).
