Biography
My research combines ecological approaches with paleoecology, geochemistry, climatology, and statistical modeling to determine the primary controls on coral reef development across a broad range of temporal and spatial scales. As a Mendenhall Postdoctoral Fellow in the Coastal and Marine Geology program, I am using cores of Holocene reef frameworks from throughout the Florida Keys Reef Tract to develop a comprehensive, millennial-scale reconstruction of reef development in this region. The overarching goal of my research program is to determine which combinations of local and global environmental conditions are beneficial or adverse to the growth of coral reefs and to use this information to help guide resource-management decisions.

Status: Active Coral Reef Ecosystem Studies (CREST)
The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Status: Active Local-scale ecosystem resilience amid global-scale ocean change: the coral reef example
Coral reefs are massive, wave resistant structures found throughout the tropics, where they have long attracted attention for their beauty, ecological importance, and rich biological diversity. However, in recent years attention to these systems has focused on their downturn in health and the potential that they effectively could disappear within a century. Yet while many coral reefs have...

7700-year persistence of an isolated, free-living coral assemblage in the Galápagos Islands: A model for coral refugia?
In an eastern-Pacific coral assemblage at Devil’s Crown, Galápagos Islands, Ecuador, two coral species, Psammocora stellata and Cycloseris (Diaseris) distorta, form dense populations of unattached colonies on sand and rubble substrata. In the Galápagos, living C. (D.) distorta is found only at this single site, whereas populations of P. stellata...

Disturbances drive changes in coral community assemblages and coral calcification capacity
Anthropogenic environmental change has increased coral reef disturbance regimes in recent decades, altering the structure and function of many coral reefs globally. In this study, we used coral community survey data collected from 1996 to 2015 to evaluate coral calcification capacity (CCC) dynamics with respect to recorded pulse disturbances for...

Improving estimates of coral reef construction and erosion with in-situ measurements
The decline in living coral since the 1970s has conspicuously slowed reef construction on a global scale, but the related process of reef erosion is less visible and not often quantified. Here we present new data on the constructional and deconstructional side of the carbonate-budget equation in the Florida Keys, U.S.A. We documented Orbicella spp...

Climate change, coral loss, and the curious case of the parrotfish paradigm: Why don't marine protected areas improve reef resilience?
Scientists have advocated for local interventions, such as creating marine protected areas and implementing fishery restrictions, as ways to mitigate local stressors to limit the effects of climate change on reef-building corals. However, in a literature review, we find little empirical support for the notion of managed resilience. We outline some...
