Uwe Hacke is a participant in the Land Reclamation International Graduate School (LRIGS) program sponsored by NSERC CREATE.

Major Responsibilities/Research Interests:

I am interested in plant responses to environmental stress, including moisture stress. Water deficits are one of the greatest challenges to tree growth and to the management of forests. Moisture deficits also limit present and future crop production in many parts of the world. Water is a topic of paramount importance for life, and our laboratory studies how plants optimize water use under different and changing environmental conditions.

I have studied water use in different biomes, including desert and temperate forest. We are fascinated by the structure of wood and how it relates to long-distance transport, but are also interested in aquaporins (membrane water channels, present in plants, mammals and most other organisms), and how their expression and activity affects water movement on a cellular and tissue level.


While the question how plants respond to environmental conditions is a central theme in our research, we work on a wide range of projects and use various methods. Our work integrates aspects of functional anatomy, molecular biology, organismic physiology, and eco-physiology.
