My research goals are to understand how the structure and spatial arrangement of plants influence ecological processes at multiple spatial scales. My work crosses multiple levels of organization, from individual plant physiology and biogeochemistry, to community and landscape ecology. My recent research has focused on how the character of a plant neighborhood (the size of neighbors, distance to neighbors, and genetic identity of neighbors) affects an individual plant's ability to access, use and convert resources into new growth. I aim to understand how these neighborhood interactions drive spatial patterns of plant growth, regeneration, and coexistence at the community and ecosystem scale. Questions I have tried answering though my research are:
Do genetically identical plants, or more closely related species, compete more intensely than more variable plants?
Does the density and age of saplings influence competitive hierarchies and patterns of succession?
How does the disturbance history of a forest create non-random patterns in tree distribution?
As soil resources become more abundant, do neighboring trees actually compete more?
My work has carried me from plantation forests in Hawaii and Brazil, to old-growth ponderosa pine forests in the Rocky Mountains of Colorado, to mixed pine-hardwood communities in Northern Minnesota.
