I am a marine ecologist broadly interested in how natural variability and human activities impact marine populations, communities and ecosystems. My goal is to conduct research that contributes to understanding and solving issues affecting marine ecosystem health while adding to the fundamentals of ecology. I use a combination of observational and experimental approaches to inform and test mathematical models of species interactions and ecosystem recovery. My research is currently focused three general areas: (1) the effects of habitat loss from anthropogenic disturbance on local community structure, population dynamics, ecosystem resiliency and recovery; (2) relationship between natural variability in habitat structure on local community structure and functioning; (3) predictability of recovery for anthropogenic disturbed habitat. I conduct my research primarily along nearshore kelp forests within the Monterey Bay National Marine Sanctuary.

Projects that I am involved in, read below
Marine PractitionersTo provide information for local, national, and international organizations on strategies to protect ocean and coastal biodiversity from degradation and depletion.
Habitat RelationshipsTo inform managers and ecologist on relationship between natural variability in habitat structure on local community structure and functioning.
Ecosystem FunctionsNatural variability in functions: habitat structure (density, size and distribution of Macrocystis sporophytes) of kelp forests and the abundance of invertebrates and fish.
