I am an avian ecologist and conservation biologist. I teach Ecology, Ornithology, and Conservation Science, all with labs. I also co-teach an interdisciplinary study abroad course in Ecuador during the summers. My research is focused on how species and communities of birds, mammals, and arthropods respond to human-induced changes in habitats and landscapes. I am also interested in how whole socio-ecological systems respond to change, and I enjoy collaborating with social scientists.

My research is focused on how ecological communities respond to anthropogenic impacts, including invasive species, habitat fragmentation, changing land uses, and climate change. I hope that my work and that of my students will contribute to the maintenance of intact ecological communities for future generations to enjoy and utilize. Humans are, in fact, part of ecosystems, and my work has evolved to become more interdisciplinary, taking into account the complexity of socio-ecological systems. I enjoy conducting research locally and throughout Latin America.
I truly enjoy interacting with diverse students and learning as much from them and the process of teaching as they learn from me. I am committed to getting students actively involved and engaged, appealing to a wide diversity of students, and incorporating ongoing assessment of both teaching and learning. Given my background in ecology and evolution, interdisciplinary scientific research and teamwork, conservation biology and sustainability, I enjoy teaching subjects around those themes. Examples of courses I may teach include ecology, introductory biology (evolution & ecology), conservation biology, behavioral ecology, ornithology, and field ecology.
