Areas of expertise
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.
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 carbonate diagenesis.
Modeling approaches include hydrological, geochemical and reactive 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, with particular emphasis on dolomitization.
Field and modeling studies have informed development an innovative model for prediction of coupled sedimentological and early diagenesis of carbonate platforms (CARB3D+), supported by the Leverhulme Trust and industry via the Bristol Carbonates Consortium.
In recent years, work has extended to CCS (carbon capture and storage) and the hydrochemistry and hydrogeophysics of volcanic systems.
