Biography

I was born in Helsinki, Finland and spent my childhood in that northern city—although my fondest memories are of summers spent among the farms and lakeside cottages of the Finnish countryside. I have my parents to thank for the decision to immigrate to Vancouver where, surrounded by the spectacular Coast and Cascade Mountains, I was able to develop my recreational interests in the mountains. After spending some years teaching Nordic skiing and mountaineering, building backcountry trails, working as a geologist’s assistant, and volunteering with a mountain Search and Rescue team, I began to develop more academic interests in mountain environments by completing a Masters degree. This involved the development of a time-lapse photography system for monitoring snow avalanche activity and snowpack behaviour in the Front Ranges of the Alberta Rockies, during which time I became acquainted with the joys of snow science at -35°C. From there I was lured into a PhD program with an invitation to join the Snow and Ice Hydrology Project (SIHP) in the Punjab Himalaya and Karakoram Mountains of northern Pakistan. This was a major collaborative project between Wilfrid Laurier University and the Water and Power Development Authority of Pakistan, and funded by the International Development Research Centre in Ottawa, with the aim of increasing understanding of the nival and glacial sources of the Indus River system. My part of the project involved researching the effect of widespread snow avalanching on seasonal snowmelt, as well as understanding the avalanche hazard faced by inhabitants and visitors in the high valleys. My five-year long involvement in the SIHP and three summers in the mountains of Khyber Pakhtunkhwa province, Pakistan have had a profound influence on my understanding of high-mountain geosystems, mountain inhabitants of the developing world, and the manner in which they deal with mountain hazard risks.

Following the completion of my PhD I landed a teaching job at Okanagan College in Kelowna, at the start of 17 years of institutional evolution which culminated in the creation of UBC’s Okanagan campus in 2005. My research over the past 26 years has primarily involved trying to understand the effects of avalanche activity on spring snowmelt, the dynamics of high-mountain fans affected by avalanches, debris flows and flash floods, and the role that avalanches play in transporting sediment into high-elevation debris flow channels. I have also had a longstanding interest in the management of mountain hazards as a component of planning for sustainable development of high-mountain environments. My various research projects have involved extensive fieldwork in the Punjab Himalaya of Pakistan, the Rockies and Cascade Mountains of western Canada and the Southern Alps of New Zealand, and studies of shorter duration in the Swiss Alps and Snowy Mountains of Australia.

Since 2001 I have also been researching tropical cyclone hazards in the Cook Islands, South Pacific Ocean—down at sea level—which goes to show that disciplinary breadth can in this instance be measured as a range of elevation! This research has produced the first-ever historical record of tropical cyclones and their human impacts in this small country, with the aim of improving our understanding of modern cyclone risk. The work is a natural extension of my interests in disaster risk reduction, although it has proved to be a significant diversion from my high-mountain research. The project was born following the destruction wrought by Tropical Cyclone Martin in 1997, the deadliest cyclone to strike the Cook Islands in 150 years, and is being carried out in conjunction with the Cook Islands Meteorological Service.
