Brief biography

Dr. David MacLean joined UNB as Dean of the Faculty of Forestry and Environmental Management (ForEM) in July 1999. Prior to that, he was a Research Scientist with the Canadian Forest Service for 21 years.

Dr. MacLean is an internationally recognized expert on forest ecology and effects of insect outbreaks on forests, and has led two national and many regional research networks including forest industry and government agencies. Much of his research has been used in forest management.

Dr. MacLean served two 5-year terms as Dean of ForEM. He has maintained a very active research program both during and after his time as Dean, with over $6.5 million of research grants and 43 graduate students supervised. Dr. MacLean has published over 190 refereed papers, and has over 4600 citations to his research papers.

Dr. MacLean was recognized with the Canadian Forestry Scientific Achievement Award in 2008, and served as President of the Association of University Forestry Schools of Canada from 2004-2006.
