Brief biography

John joined the faculty in 1991. Prior to moving to New Brunswick, he worked in forestry in Indiana, Wisconsin, and Washington State. John’s speciality is forest mensuration, forest inventory design and analysis, and growth and yield modeling. John has pioneered the application of copulas, a special class of multivariate distributions, in forest inventory, LiDAR analysis, and growth modeling. He currently has research projects in New Brunswick, Newfoundland, Maine, Florida, Oregon, Malaysia, Taiwan, Indonesia, and India. He is the lead author on the 5th Edition of Forest Mensuration (Wiley-Blackwell, 2017), the most widely used mensuration book in North America.

John is currently the Assistant Vice President Academic (Partnerships) at UNB, but continues to have an active and growing research lab. John teaches Advanced Mensuration, Research Methods, Forestry in Atlantic Canada, and coordinates the Nanjing Forest University – UNB 3+1+1 program. John is UNB’s representative to the Indo-Canadian Shastri Institute. He enjoys world travel and forging new partnership opportunities for UNB. He is a member of the editorial board for Forest Ecosystems. When he is not being a forester or assistant VP, he is an avid hiker, canoeist, and mountain climber.
