Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

My career in science started with the study of marine biology, and now includes work in hydrology and watershed science. I am interested in the sustainability and biodiversity of Pacific Island ecosystems, with attention to the links between terrestrial ecology, watershed hydrology, and coral reefs. I have written scientific papers on subjects such as ground-water contamination, seawater chemistry, underwater volcanism, and coral reef ecology. I started working for the USGS in 1988 as a laborer on a drill crew. In 2010, I became the third Director of the USGS Pacific Island Ecosystems Research Center, where I have the privilege of working with an exceptional group of researchers that provide information to understand, conserve, and manage natural resources on Pacific island ecosystems.
