New Brunswick Energy Institute names interim replacement for Louis LaPierre

SAINT JOHN, N.B. - The New Brunswick Energy Institute has chosen an interim chairman to replace Louis LaPierre, who quit after admitting he misrepresented his academic credentials.

David Besner, a professional chemical engineer and a former assistant deputy minister with the provincial government, takes the job effective immediately.

Energy Minister Craig Leonard says Besner is a member of the scientific advisory council for the energy institute.

The institute is studying the shale gas industry.

In various biographies, LaPierre said he had a doctorate in ecology from the University of Maine, but the school says it has no record of him earning the degree.

Premier David Alward says the energy institute now has a perceived lack of credibility and work must be done to rebuild its reputation.
