Research Focus

My current research is focused in two subject areas: 1) resolving depositional cyclicity and evolution of convergent-margin basins (CMBs); and, 2) evaluating fluvio-tidal strata through time and space.

My work on CMBs is focused in two areas, the Georgia Basin, Vancouver Island, Canada and the Western Foreland Basin, Taiwan. In the Georgia Basin, my students and I are developing a basin-wide sequence stratigraphic architecture for terrestrial- to shallow-marine strata of the lower Nanaimo Group using outcrop exposures, subsurface cores, and detrital zircon. The sequence stratigraphic model replaces the existing lithostratigraphic model, and provides a detailed record of the evolution of the Georgia Basin and CMBs in general. Using the stratigraphic model, detrital zircon geochronology, and biostratigraphy, we are also evaluating the early evolution of the Georgia Basin to gain additional insights into the tectonic evolution of western North America. In the Western Foreland Basin (WFB), Taiwan we are undertaking highly detailed stratigraphic analysis of Pliocene to Pleistocene, terrestrial- to shallow-marine strata to resolve depositional and climatic cycles. The Taiwan research is focused on determining how CMBs evolve, and the dominant controls on sedimentation therein; this work forms part of the research being conducted by the international research consortium that i co-founded: Paleoclimate Records In Shallow-Marine Strata (PRISMS).

Work on fluvio-tidal deposits is present focused in the rock record, and specifically on the oil sands-hosting McMurray Formation, Alberta, Canada. This work is part of a large research consortium between academia and industry aimed at resolving the architecture of the McMurray Sub-Basin, the end result of which will be a basin-wide sequence stratigraphic model of the Athabasca Oil Sands, and characterization of complex, stacked fluvio-tidal strata. In the modern, I continue to conduct research of the Fraser River and Delta.

My prior research focused largely on characterizing modern analogs for marginal-marine sedimentary strata, with work on fluvio-tidal systems and estuaries (Fraser River, Canada; Gironde Estuary and Arcachon Bay, France; Columbia River, Willapa Bay and Tillamook Bay, USA; Mitchell Delta, Australia) tidal shorefaces (Bay of Fundy and Vancouver Island, Canada), and deep-water asymmetric deltas (Fraser River Delta, Strait of Georgia, Canada). My modern research included both sedimentological and neoichnological characterizations of these environments, and the results were used to construct and refine sedimentological and ichnological facies models that aid in the interpretation of sedimentary rocks in outcrop and in the subsurface.

I have also led projects conducting facies analysis and reservoir quality characterization of CO2-enhanced oil-recovery projects and tight-oil reservoirs, and facies charatcerization of the oilsands-hositng McMurray Fm. All of the sedimentary rocks hosting these petroleum products were deposited in shalllow-marine depositional environments.
