Professor, Forest Entomology
Director, Forest Sciences Undergraduate Program
ABOUT ALLAN
DR. ALLAN CARROLL is an insect ecologist, Professor, and Program Director based at the University of British Columbia in Vancouver, BC, Canada. Allan has over 30 years of experience researching the biology, evolution, ecology, dynamics and management of forest insects across Canada.
Allan spent the summers of his formative years in a remote part of British Columbia’s Chilcotin Plateau where he developed his passion for forest ecology and entomology. This passion extends beyond his profession to his personal life, and he spends much of his free time exploring the diverse ecosystems of western North America, from Mexico to the Arctic – usually on a motorcycle.
“My fundamental research interests are driven by the seeming paradox that long-lived plants remain abundant and largely intact despite the apparent evolutionary advantage of most insect herbivores arising from their short generation time and enormous recombination potential.”
-Dr. Allan Carroll
RESEARCH
ALLAN’S RESEARCH INTERESTS focus on (1) the effects of climate change on forest insect pest disturbance regimes, (2) bark beetle population dynamics, (3) the risks associated with the migration of mountain pine beetle into the boreal forest, and (4) the development of emerging techniques for the detection and monitoring of forest insect pests. Allan is considered an expert on the population dynamics and ecosystem impacts of eruptive forest insects- most notably with the mountain pine beetle. As of February 2020, Allan has authored/co-authored over 75 peer-reviewed papers, chapters and reports.
TEACHING
ALLAN CONSIDERS HIMSELF incredibly lucky to teach the next generation of environmental stewards and strives to challenge each student to think critically within his classes through open dialogue. Allan’s teaching philosophy centers around the utilization of real-world examples to enhance learning and class engagement. Allan typically teaches/co-teaches several core courses: FRST 307 (Biotic Disturbances), FRST 408/508 (Advanced Forest Insect Ecology), and FRST 557 (Site-Level Forest Land Management). He also coordinates FRST 498 (B.Sc. Thesis in Forestry). Allan has supports many students interested in topics beyond the standard curricula by offering supervision for Directed Studies (FRST 449) in topics related to insect ecology.
PUBLIC ENGAGEMENT
ALLAN VALUES EFFECTIVE SCIENCE COMMUNICATION as an avenue for public engagement with science. As a Senior Federal Spokesperson during his time at the Canadian Forest Service, Allan responded to national and international media inquiries, and liaised with NGOs and governments at all levels. Allan’s research and expertise on the mountain pine beetle has been featured in outlets like The Nature of Things (‘Climate Change: An Uncertain Future’, 2007; ‘The Beetles are Coming’, 2014) and National Geographic (‘The Bug That’s Eating the Woods, 2015’). He has also been invited to speak on issues of climate change and forest disturbance at the United Nations Economic Commission for Europe (Geneva), and the European Commission (Brussels), as well as presentations to both the Conservative and Liberal caucuses in Ottawa.
