Global Environmental Change and Ecosystem Dynamics
Web Link
My primary research interest involves understanding how global environmental change (land-use and land-cover change and climatic variability) alters the structure, function, and distribution of terrestrial ecosystems. I focus on hydrologic and biogeochemical cycling and vegetation dynamics, primarily in high-elevation tropical landscapes.

Ecosystems: Structure, Function, Services
Ecosystem science examines the interactions between organisms and the physical environment as an integrated system and seeks to understand the factors that regulate the quantity and flow of materials and energy through ecological systems. In this course, you will learn about the structure of ecosystems (how they are built), the function of ecosystems (how they work), and how those structures and functions translate into environmental goods and services. The course is divided into four modules. The first brief module is a basic introduction to ecosystem concepts and the geography and structure of major ecosystem types. During the second module, we will begin evaluating how ecosystems work or “function”. We will begin by examining the first main branch of ecosystem science, which is concerned with understanding the flow of energy through ecological systems. During the third module, we will study how materials, namely water, carbon, nitrogen, and phosphorus, cycle through ecosystems. During the fourth module, we will revisit some basic ecosystem concepts and examine case studies of ecosystems in a context of global environmental change. Students will present papers and posters on a topic of interest.

Global Environmental Change (GEOG 5700)
This course will explore current scientific, societal, and policy perspectives on key issues of global environmental change. Themes of interest include climate change, land-use and land cover-change, terrestrial and ocean acidification, and renewable energy. Readings from a variety of sources, written assignments, class lectures, and round-table discussions will be used to challenge students to critically examine the scientific evidence for these phenomena and the attendant consequences for Earth’s physical, chemical, and biological systems. A variety of perspectives and policy responses to global environmental problems will be compared, assessed, and debated following student-to-student exchange of written commentary. Graduate student enrollment is capped at 15 students.

Introduction to Earth Science (GEOG 1710)
The Earth is a complex and interacting system of air (atmosphere), water (hydrosphere), rock (lithosphere), and life (biosphere). This course will provide an introduction to the study of Earth and its components, and in particular to the physical and biological factors that create the biosphere in which we live. The goal of this class is to provide you with a basic, yet comprehensive, understanding of your physical environment. Course Objectives - To examine spatial patterns of landforms, water, vegetation, soils, and climate across Earth’s surface. - To understand the processes that influence spatial patterns and interactions in the environment. - To study the Earth as a complex and dynamic system, shaped by internal and external environmental processes and human activities. Learning Outcomes - Learn basic scientific concepts and theories from the various disciplines that make up the earth sciences (e.g., geography, geology, ecology, and hydrology). - Identify physical features and landforms and understand the processes that give rise to those features. - Understand the value and underpinnings of a systems approach. - Increase knowledge of current local, regional, and global environmental issues.
