I am a marine conservation ecologist with particular interest in anthropogenic disturbances on ecosystem functioning and community structure of coastal habitats. Given the high population of humans in southern California, urban coastal ecosystems are subjected to numerous human impacts. Work in my lab attempts to understand how these systems are changing and functioning in the face of these disturbances. I apply my conservation interests mostly to rocky intertidal ecosystems, focusing on invasive seaweeds; effects of human visitation; long-term change in community structure and dynamics; effects of climate change; restoration ecology, and environmental policy and management (such as Marine Protected Areas). The research questions addressed have implication in policy making decisions, particularly with current emphasis being placed on Ecosystem Based Management. Recently, focus has been placed on introduced seaweeds, including determining their impact on community structure, how they fit into native food webs, and examination of transport vectors.
