Structural controls affecting potential petroleum systems in Devonian-Carboniferous basins of New Brunswick
Funded by NB Department of Natural Resources, NSERC Collaborative Research Grant, Petroleum Research - Atlantic Canada, and Corridor Resources Inc.

Biogeochemistry, diagenesis and chemostratigraphy of shale and oil shale, eastern Uinta Basin, Utah, USA
Funded by the Utah Geological Survey
Shale and oil shale of the Green River Formation includes several beds that have undergone phosphatization, apparently by different processes, including microbial activity.  These rocks are being examined for toxic metal enrichments, and correlated by LA-ICP-MS, XRD, SEM, TEM – and likely other techniques as well!

Teaching

“I got back from Houston recently and I thought I should thank you because I wouldn’t have had any clue what anyone was talking about without your help. From not knowing anything about the petroleum industry to being part of it, your class was a crucial step and I think you did a bang-up job of it. ...I will be moving to Houston to train as a geophysicist next summer.”
– former student, now working with a natural gas company (Texas).

“I just took a geoscience recruitment short course with Imperial Oil over this past weekend... Despite the fact most of the candidates were graduate students with advanced degrees, I was approached by instructors and highly complimented on my knowledge and skills in the petroleum geosciences. I just wanted to say thank you for preparing me so well in the course and I appreciate all the work you put into teaching me what I need to know for industry.”
– former student, now working with a petroleum consultancy firm (Alberta).
