I am broadly interested in plant resource allocation and its implications on plant life history traits and performance in the field. Within this general framework, my students, collaborators and I have engaged in different research adventures. We have examined the interaction of hydraulic, physiological and structural traits in different conifer species and habitats in Northern Rocky Mountain forests. We are also exploring whether and how internal resource dynamics influence life history strategies in plants (e.g. masting and prolonged dormancy). Another major focus in our lab has been the analysis of the consequences of fire exclusion and active forest management on forest structure and function in mixed ponderosa pine forests. While the initial focus of this research was to examine tree responses to alterations in resource availability, we have also done work on how past management has influenced current forest structure. I am becoming very interested in the interaction between plant resource allocation (including to storage) and responses to drought.
