Job/Research Area

Plant Biology

Major Responsibilities:

I am currently serving as Graduate Program Coordinator in the Department of Renewable Resources.

  • David J. Gifford Award in Tree Biology from the Canadian Society of Plant Biologists (2017)
  • CD Nelson Award for outstanding research contributions to plant biology, Canadian Society of Plant Biologists (2013)
  • Faculty of Agricultural, Life & Environmental Sciences - Teacher of the Year (2008)
  • Tier 2 Canada Research Chair in Tree-Water Relations (2007-2016)


Research Interests:

I study trees, water, and vascular transport. Trees provide us with oxygen, habitat for birds and other animals, shelter, and wood products. Water is the molecule of life; as such it plays an active role in a myriad of processes on the cellular and organism level. Vascular transport distributes water and other molecules across the plant body.

In contrast to the human cardiovascular system, trees need to maintain their transport systems over decades and centuries, time scales that may greatly surpass human life spans. Such transport systems must cope with environmental changes and adjust to the growth of the organism over time.

I ask: How do these transport systems function? How do drought, frost, and insects affect transport? How are transport processes influenced by rising temperatures and concomitant changes in climate?

Research keywords:
  • xylem/wood
  • drought
  • tree rings
  • aquaporins
  • phloem
  • frost
  • plant abiotic stress
  • climate change


I teach courses on Introductory Plant Science and Graduate Research Skills.
