My work focuses on three goals: increasing our understanding of the forces that shape and reshape the organisms and ecosystems around us, increasing our understanding of the way these organisms and ecosystems shape and reshape us, and building our capacity to collectively mobilize knowledge in the service of sustainability.

My research focuses on the movement of individuals, populations and communities. I am interested in both the causes and constraints on movement (from climate change and connectivity to fragmentation and life-history) and the consequences of movement for gene flow, hybrid zone formation and movement, and community cohesion.

I would consider myself as a broadly interested community ecologist who looks beyond the end of his nose. Throughout my scientific career, I investigated trophic interactions which were mainly focused on arthropods. These interactions were either based on pollination or herbivory and predation.

I am interested in using both field and quantitative methods to address applied questions in the conservation and management of biodiversity. I am now collaborating with the Natural Capital Project using terrestrial InVEST models to assess the impacts of varied land-use scenarios on threatened and endangered species on Department of Defense lands.

We live in a fragmented world, and mitigating the effects of habitat fragmentation is one of our greatest conservation challenges. I am a broadly trained environmental biologist, and my interests sit at the interface of conservation biology and conservation policy.

I am broadly interested in natural history ecology, plant-fungal interactions, and coevolution. My research focuses on how reciprocal evolutionary change between interacting species shapes the ecological dynamics of communities and maintains biodiversity. Much of this work focuses on fungal pathogens of wild chilies in Bolivia

I am interested in the ways that ecology has shaped the evolution of plant-animal interactions. These interactions are particularly important when they underlie organisms vulnerability or resilience to environmental change. My research is currently focused on the loss of seed dispersal mutualisms.
