An expert on the natural-gas boom is again facing criticism over his ties to industry and the lack of transparency in how he presents work to the public, the Associated Press reported this week.


Timothy Considine was the lead author of a shale-gas report recently issued by the University of Buffalo and a previous report from Penn State University.


Critics say both reports presented research in misleading ways and failed to fully disclose funding sources.


Considine is now at the University of Wyoming.


He has gotten funding from the Marcellus Shale Coalition, the Wyoming Mining Association, the American Iron and Steel Institute and the American Petroleum Institute.


His work at Buffalo have been criticized by the Public Accountability Initiative, a Buffalo-based non-profit group.
