Biography, Education and Training

Career Goals:

Increase knowledge of intertidal zonation patterns and species interactions

Analyze data to detect and understand spatial and temporal patterns as they relate to community structure and species diversity within the intertidal

Streamline protocol and the flow of information between ongoing research projects to reduce overlap and redundancy, and increase efficiency in planning and organization

Organize data to make information more accessible and valuable for other technicians, researchers, policy/decision makers, and the public


1997 B.A. - Marine Biology, University of California, Santa Cruz

Selected Projects:

(2021) Create web based data entry forms for Citizen Science and other Collaborative Monitoring groups to enter sea star data. Created database and associated map to track coastal visitation inside and outside Marine Protected areas.

(2020) Incorporated data from partner research groups into MARINe Database (e.g. Audubon; LiMPETS). Completed topography maps for biodiversity survey sites and added to website.

(2019) Develop process to update temperature data up to 2017 and upload to DataONE Repository; coordinate with the state of California and the Ocean Protection Council to develop a data repository and upload mechanism for long-term monitoring of California Marine Protected Areas

(2018) Complete iOS data collection apps for Point Contact Biodiversity Survey data and Layered Photo Plot Long-Term Monitoring Survey data; begin preparations for publishing to app store

(2017) Perform QA/QC of the South Coast and North Coast Marine Protected Areas baseline monitoring data packages; Create web based data entry forms for MARINe Database

(2015-present) Work with outside groups (NPS, USGS, GFNMS, Audubon, etc.) to incorporate their data into the MARINe database; this work is ongoing

(2013-2014) Added additional project to to specifically document Sea Star Wasting Syndrome (, including a way to document observations and display these observations and associated data on a map.

(2013) Upgrade of existing MARINe (Multi-Agency Rocky Intertidal Network) Access database to new format (MySQL), including researching options, determining server space, building in data checks and enhanced QA/QC. This is a multi-year and multi-tiered project, with future goals including web-based data entry and data retrieval and display.

(2012) Launched intertidal website (, which displays information about research sites and species, and allows for data display and mapping. Continually update website with current information and trend graphs, as well as responding to data requests.

(2010-11) Creation of Data and Metadata Standard document for the North Central Coast Marine Protected Areas Baseline Program. This document was used as the template for the South Coast Marine Protected Areas Baseline Program in 2014-15, with the potential to be extended to the entire California coast and beyond. This document instructs research groups to submit and describe their data in a consistent way to allow for future analysis.

(2009) Used abalone habitat assessment data to calculate the rocky shoreline (using ArcGIS) available for abalone habitat along the California coast.

(2008) Organized MARINe (Multi-Agency Rocky Intertidal Network) data to be loaded into web based data catalog (

(2006-2007) National Park Service Coastal Biophysical Inventory: Work in conjunction with the National Parks Service to review and enhance protocol for the Coastal Biophysical Inventory project and initiate field surveys for training purposes. This project included mapping the coastal areas of Point Reyes and Golden Gate National Parks, including physical and biological characteristics of the entire shoreline.
