I am a marine ecologist working with communities and agencies to integrate science with conservation and management. I focus on how human disturbances affect marine ecosystems through both direct and indirect mechanisms and ways we can mitigate impacts. My previous empirical work has focused on trophic cascades (how the removal of top predators changes grazer abundance and consequence for ecosystem structure and function) and on invasive species dynamics. I am currently the lead scientist for a non-profit OneReef, helping communities develop locally managed marine protected area monitoring plans in the tropical Pacific. I am also the co-director of the Adaptive Management Program for the Kenya Wildlife Service. This program (currently in the Mombasa Marine Park and Reserve and expanding to the Kisite park) helps marine protected area managers use data to make proactive management decisions. As a Research Associate at the University of California Santa Cruz, I am working on several publications related to coral resilience and which genera have survived over geological time. I am also collaborating with the California Department of Fish and Game on the response of crustose coralline algae to ocean acidification, and which species have a role in abalone and other invertebrate settlement. I recently helped develop another collaborative effort to investigate the roles of large and threatened herbivores (bumphead parrotfish) on coral reef community structure in the Solomon Islands.

BREAKING NEWS!
"Where have all the Reef Fish Gone?"
I'm participating in a new way to to support scientific research and raise awareness called the SciFund Challenge! In a 3 minute video, I describe one of my current research projects focused on fish tagging in Kenya. The objective is to determine if fish movement beyond park boundaries into fished areas is preventing full recovery of the Mombasa Marine Protected Area.

Marine Ecology Progress Series (MEPS) Coral Reefs Professional Experience
I was a postdoctoral researcher at the National Science Foundation's National Center for Ecological Analysis and Synthesis (NCEAS) where I worked with a team of international scientists on a global model of the ecosystem services provided to humans by maintaining healthy oceans. As part of this work, I developed a case study using the model for the island nation of Fiji.
I was a postdoctoral researcher at the American Museum of Natural History's Center for Biodiversity and Conservation. In this capacity, I worked with the Kenya Wildlife Service to develop the Adaptive Management Program in the Mombasa Marine Park and Reserve. The program integrates science with management and is now used as a model for all of Kenya's marine parks. I was formerly a marine biologist with the California Department of Fish and Game (1999-2002). In this capacity, I was a principle co-author on the state management plan for seven species of abalone. I was also the first biologist hired by the Napa County Resource Conservation District and developed a watershed wide salmonid habitat assessment program and a volunteer monitoring program. I am a former AmeriCorps volunteer with the Watershed Stewards Project and was a volunteer with Children International in Ecuador, where I developed and carried out a project to transform a dumping site to a community park.
