I am a plant ecologist with a broad interest in how anthropic activities influence forest succession, biological diversity, and ecosystem services.  More specifically, I am interested in the dynamics of two types of plant populations: (1) exotic introduced species, in the context of North American invasion ecology, and (2) rare and threatened indigenous species resulting from habit loss, fragmentation, and climate change.  In many ways these populations types exist on opposing ends of a stability continuum (quiescent invaders vs. waning natives), yet the processes governing their survival remain the same and allow for similar research methods.

 My research utilizes experimental and observational approaches to assess the dynamics of populations and individuals within natural and cultivated (ex situ) sites.  Given that the majority of plant invaders are introduced through the horticultural trade, botanic gardens and arboreta provide a valuable resource for the study of living and preserved collections.  I am especially interested in seed biology and ecology, the factors that influence seed viability, dormancy breaking requirements, and primary- and secondary dispersal vectors.  These data provide valuable insight for modeling population growth and survival, as well as methods for restoration efforts.
