Research interests

Dave is active in both microbiogeochemical and sedimentological research, specializing in the study of non-skeletal carbonate precipitation and the application of this research to large-scale, land-based carbon sequestration. Dave is also a geological consultant to the hydrocarbon industry, specializing in reservoir characterization studies using the evolved technique of high resolution heavy mineral analysis.
