Research Interests

The formation, fill and economic resource potential of ancient sedimentary basins is the primary focus of my academic research. To understand the linkages between tectonics, sedimentary process and basin dynamics, I use an integrated approach using a range of datasets. Typically, I use a mixture of outcrop, seismic, well-log and core in my research. The methods I use include detailed sedimentology, regional-scale outcrop-to-subsurface sequence stratigraphy, geologic mapping, provenance analysis, and paleocurrent analysis. Geographically, my research is centered in the Rocky Mountain Region. Because much of my work is mega-regional (hundreds to thousands of kilometers), I'm currently investigating stratigraphic problems in Montana, Wyoming, Colorado, Utah, northern Arizona and eastern California. Stratigraphically, I'm interested in the Mesozoic with considerable past and current research in the Cretaceous, and recent interests developing in the Permo-Triassic. 

Core research themes that I am currently pursuing:

1. Understanding basin dynamics and their fill- especially the role of dynamic subsidence,
2. Applied stratigraphy and sedimentology as it pertains to the oil and gas industry,
3. Unconventional resources such as shale, tight-gas and tight-oil.

Recent Synergistic Activities

1. 2014 First Annual UAA Core Workshop

-undergraduate students presented their core descriptions/interpretations to local industry professionals and the general public in the Anchorage community. Students were evaluated on their technical content, poster presentations and ability to communicate with specialists and non-specialists from the community. Participants ranged from elementary school students to volunteer judges from USGS, ConocoPhillips, BP, AK Division of Oil and Gas, and UAA.

2. 2014 Alaska Geological Society Presentation
3. 2014 BP Energy Center Presentation
4. 2015 ConocoPhillips Center Presentation
