Research Interests:
My research is focused primarily on climate variability and its role in driving biological and physical components of mountainous ecosystems of western North America. In addressing these issues I use instrumental and tree-ring based records of climate to assess the time intervals and spatial scales over which these processes operate. Of particular interest is the influence of interdecadal climate regimes, long-term temperature trends, and ocean-atmosphere teleconnections in driving observed changes in mountain snowpack, streamflow, glaciers, and forest disturbance events. Recent studies have addressed the susceptibility of natural resources within national parks and protected areas to climate variability and change, and sought to apply both the modern and paleoclimatic records to present day resource management problems.
