My research strives to advance fundamental scientific knowledge on forest dynamics, which is imperative for conserving and managing contemporary forests and adapting to global environmental change. My research characterizes how natural disturbances, humans and climate interact to drive temperate forest dynamics and resilience. It has produced three key contributions:

(1) My international collaborations demonstrate widespread tree mortality in North and South America, disentangling the relative impacts of drought, insects and pathogens.

(2) Many forests in the Canadian Cordillera are increasingly susceptible to wildfire due to complex interactions among fire suppression, land-use and climatic change.

(3) My novel forest reconstructions include tree-ring methods adapted to address aboriginal cultural uses and traditional management, largely overlooked by forest managers.

My enduring partnerships with local to national governments, environmental organizations, forest management companies, community forests, and First Nations have helped me translate these scientific advances to operational conservation, restoration and management policies and practices.

Current Courses



I aim to inspire students to be active learners, reach high levels of achievement, and graduate with the confidence to pursue their lives as globally-aware leaders. My holistic approach provides opportunity for students at all levels of scholarship. My undergraduate teaching includes reflective and experiential learning in lecture. I use problem-based learning in the field and lab to reinforce and complement the theory learned in the classroom. Integrating research with learning, I have mentored 46 post-graduates and 100 undergraduates at UBC, each gaining high-quality research experience and developing specialized skills in dendrochronology (tree-ring science). As an educator, my career extends beyond traditional university teaching and learning as I have developed comprehensive outreach programs for forest professionals, the general public, school groups, and aboriginal youth. My students, through their integral involvement in 22 outreach events since 2003, have gained invaluable career-shaping experience interacting with forest managers and aboriginal communities.
