Current Research

My research focuses on understanding the response of ecological systems to changing and altered landscapes. I work at a variety of scales and use a multitude of quantitative tools to address questions of climate change impacts and avian migration.

Climate Change research: our efforts have focused specifically on modeling the response of 147 bird species' habitats and 134 tree species' habitats to climate change across the Eastern United States. As our modeling efforts continue, we are striving to create decision support tools to integrate and synthesize this work for the public and land managers.

Avian Migration: I am exploring questions on the habitat requirements and behavioral decisions of migrant birds during migratory stopover within rapidly urbanizing metropolitan areas.

Research Interests

I plan to continue my current research, and I would like to expand the breadth of my focus to include other taxa. In addition, I hope to contribute to new research areas where I can apply my interest of quantitative ecology to gain further perspective of how landscape changes may influence ecological communities.

Why This Research is Important

With greater awareness that global climate change is becoming reality and that urbanization is increasing worldwide, both of these research avenues represent areas of increased importance within the field of landscape ecology.
