Research Interests

We are broadly interested in the physiological basis of plant performance in nature, with a special focus on plant resource dynamics and its implications on life history strategies and responses to the environment (including drought, fire and bark beetles). We mostly focus on trees, particularly conifers, though we have studied other interesting plant forms. Our research is mostly driven by curiosity to explain patterns in nature.  Some questions that keep us intrigued include:  Are stored nonstructural carbohydrates important for plant water relations and responses to drought? If so, why?; Why do inherently slow growing trees live to older ages? Why are faster growing trees less resistant to environmental stresses?; What are the consequences of alteration of fire regimes on resource availability and tree performance, including defenses against pests and responses to drought?
