Christain Giardina is a Research Ecologist with the Pacific Southwest Research Station of the USDA Forest Service in Hilo, Hawaii. His research focuses on experimental and large-scale gradient studies to understand how global change will impact tropical forests and their restoration. Research has examined the impacts of increasing CO2, changes in temperature and precipitation, fragmentation and afforestation on ecosystems. He has served as co-principal investigator or project director for research supported by the US Department of Energy, the US Forest Service, and the National Science Foundation. He has authored or co-authored 50 peer-reviewed journal articles and book chapters, and has taught courses in ecosystem ecology, forest ecology, climate change; agroforestry, and forest management.
