As tropical forest ecologist, my research interests revolve around understanding how tropical forests are structured and how tropical ecosystems function. I have been fortunate to work in both Latin America and Hawaiʻi.
Current research projects include:
- Designing hybrid ecosystems as a restoration strategy
- Could hybrid ecosystems save native forests in Hawaiʻi?
- The Applied Ecologist’s Blog
- Read more about the Liko Nā Pilina project on our website
- Hawaiian forest dynamics using long-term permanent plots (see HIPPNET project)
- Significance of foliar N and P accumulation in tropical forests
- Species invasions and their effects on nutrient cycling
Our lab group works on a variety of ecological studies.

I currently teach ecology courses at both lower and upper levels. In lower level courses, the emphasis is on developing a solid foundation based on ecological theory and to understand how that theory can be applied to present environmental issues, particularly related to global change. In upper level courses, the focus is on learning about the “art” of science, including reading primary literature, discussion of new analytical tools, and development of independent hypotheses and research proposals. All laboratory courses that I teach are field based, and take advantage of the extraordinary landscape diversity of the Big Island of Hawaiʻi.
Career Resources for UH Hilo Students
I am involved in an NSF grant (DEB, Ecosystem Studies, # 0546868) in which I am developing career resources for students interested in the environmental sciences.
