As a research scientist for the Coastal and Marine Geology Program, I investigate the causes and effects of coral reef degradation. I seek to increase understanding of local and global-scale stressors on reefs, and experimentally determine how environmental variables such as sea-surface temperature, water quality, seawater chemistry, nuisance macroalgae, and ocean acidification affect coral reef organisms and community structure. My work informs resource managers about the mechanisms causing reef degradation and how management efforts may be improved to protect and restore degraded reefs. Please visit the USGS Coral Reef Ecosystems Studies (CREST) website for more information: http://coastal.er.usgs.gov/crest/.
