My research focuses on carbonate sedimentology and diagenesis, integrating field studies of modern environments with numerical modeling, to provide a holistic understanding of the evolution of porosity-permeability in carbonate sediments from birth to burial. My work has included application of these techniques to understanding restless volcanic systems and CO2 sequestration in reservoirs and aquifers. Recently I have focussed on understanding the impact of climate and land-use change on the hydrology of coastal and island aquifers.

Field studies in the Bahamas, Yucatan and Guam include aqueous biogeochemistry, hydrological monitoring and aquifer characterization, and enable quantification of key processes and evaluation of fundamental controls on hydrology, geochemistry and water-rock interaction, with application to hydrogeophysics. 

Modeling approaches include hydrological, geochemical and reaction transport modeling (RTM). The latter, an emerging technology which simulates geochemical reactions in systems open to fluid flow, is providing exciting new insights into a range of rock-water interaction systems. Field and modeling studies have informed development an innovative model for prediction of coupled sedimentological and early diagenetic evolution of carbonate platforms (CARB3D+).
