Education

I have Ph.D. and M.S. degrees in geoscience from the University of Washington and a B.A. in biology from Oberlin College.

Teaching

Since 2012, I have taught classes on rivers (Fluvial Geomorphology, ESS 426/526, Applied Fluvial Geomorphology, ESS 541), writing (Technical Communication in Applied Geosciences, ESS 518), and environmental history (Changing Rivers of Puget Sound, ESS/AIS/ENVIR 310).

I also advise students in the applied geoscience M.S. degree program (Masters in Earth and Space Sciences, Applied Geosciences or "MESSAGe"), an 18-month program that includes coursework, an internship, and an applied investigation capstone.

Research

I use geomorphology along with environmental history, ecology, and hydrology to study the interacting physical, biotic, and human elements of rivers and their landscapes and how they change through time. Much of my research has application to fisheries, forestry, river and watershed management, environmental restoration, or natural hazards.

Current projects: (a) colleagues in engineering and geoscience and I are seeking to better understand sediment production, routing, and channel response and to incorporate that understanding into improved flood modeling capabilities; (b) I am working with post-doc Dan Scott and collaborators at the US Forest Service to evaluate wood jam dynamics and geomorphic change for stream restoration; (c) with colleagues in geoscience, anthropology, and archaeology I am investigating how traditional and modern land uses have affected soil erosion and channels in SW Sichuan and, in northern Sichuan, interaction between Holocene loess deposition, landsliding, and human settlement; (d) data mining archival sources to reconstruct historical hydrology, channel geomorphology, and riverine habitats in the Puget Sound region.
