Current Research

In my current work, I am evaluating metrics to determine the effectiveness of channel restoration and am measuring the sources of carbon in the hydrologic cycle. I also am assessing alpine timberline advance by evaluating site temperature, site moisture, plant water relations, and stomatal conductance.

Research Interests

Multi-scales of hydrology, from water in individual plants to evaluation of water amount and quality in soils and stream systems; abiotic (nonliving) and biotic (living) linkages; and the role of disturbance in habitat and microsite creation.

Past Research

My past research has focused on landslide initiation, runout, and deposition in old-growth, second-growth, clearcut, and yellow cedar decline forests; effects of landslide dam-break floods on channel morphology; and effects of disturbance on tree species, throughfall, and large woody debris recruitment in channels.

Why This Research is Important

My research is working toward an understanding of whole-system water relationships, which is integral to detecting influences of both management practices and climate change on water and forest pattern. A better understanding of factors influencing water can help us to develop improved restoration techniques and to guide strategies for planning into the future.
