I am a plant ecologist interested in the effects of climate change on forest communities.

I teach BIOL 0140 (ecology and evolution), BIOL 230 (global change biology), BIOL 323 (plant community ecology), as well as a variety of first-year and senior seminars that explore ecological history, climate change, and land-use change in Vermont. In my research, I use tree rings to understand how changes in climate affect the growth and population dynamics of tree species in Alaska and Siberia. I have collaborated with numerous Middlebury students over the years to study how changes in disturbance regime have affected an old-growth hemlock forest, the Battell Research Forest, in central Vermont.  Follow this link to read more about my research in Vermont and Alaska.

AMST 0295 - Across the Great Divide      

Across the Great Divide: Science, Humanities, and the American Landscape
The American landscape encompasses a diversity of built and natural environments. In this course, we will survey 200 years of history, using the tools of science and the humanities to understand how people have changed the landscape and how the landscape has shaped its human inhabitants. We will read historical, literary, and scientific works—and employ a variety of archival and aesthetic materials—to explore moments of transformation within four geographic regions: New England, the Midwest, the West, and the South. In so doing, we will arrive at an understanding of the interdependency of cultural and ecological history and the intersections between scientific and humanistic modes of inquiry. Readings will emphasize primary texts, and will include writings by Harriett Beecher Stowe, George Perkins Marsh, and photography by Dorothea Lange and others. AMR HIS NOR

AMST 0300 - Everglades History and Science      

Reclaiming the Swamp: History, Science, and the Challenge of the Everglades
In this course we will survey the cultural and ecological history of the Everglades, starting in the early 19th century and culminating in current restoration efforts. A critically endangered ecosystem, the Everglades illustrates the concept of a “wicked environmental problem”: one characterized by high uncertainty and conflict over values. Following our historical survey of the Everglades, we will shift to a project-based investigation of the local and global forces that shape the region. Course materials will be drawn from fiction, art, historical studies, policy documents, and scientific literature. Students should be prepared to work collaboratively to engage a variety of primary sources. 3 hrs. lect./disc. AMR HIS NOR

BIOL 0230 - Global Change Biology      

Global Change Biology
We will examine the effects of global climate change on the earth system. Our emphasis will be on exploring what we know about the impacts of climate change on ecosystems, and how we know it: how do biologists study processes on a global scale? How accurately can we predict future changes in ecosystem distribution and function? We will also delve into how changing ecosystem processes are likely to affect humans, through impacts on ecosystem services, for example. The course will culminate with an examination of science communication, and students will engage in independent projects to practice the art of effective science communication. (BIOL 0140) 3 hrs. lect. SCI

BIOL 0701 - Senior Thesis      

Senior Thesis
Seniors majoring in Biology who have completed one or more semesters of BIOL 0500 or BIOL 0700 and who plan to complete a thesis should register for BIOL 0701. In this course students will produce a written thesis, deliver a public presentation of the research on which it is based, and present an oral defense of the thesis before a committee of at least three faculty members. Additional requirements include attendance at all Biology Department seminars and participation in any scheduled meetings with disciplinary sub-groups and lab groups. Open to Biology and joint Biology/Environmental Studies majors. (BIOL 0211 and BIOL 0500 or BIOL 0700 or waiver; instructor approval required for all students) 3 hrs. disc
