My research focuses on using geochronology, remote sensing, and modeling to understand the timing and rates of surface processes. Much of my work involves cosmogenic dating and optically stimulated luminescence (OSL) dating. In 2013 I founded an OSL lab at Middlebury, which is open to visitors and collaborators. Recent projects have looked at spatio-temporal patterns of erosion, neotectonics, and terrestrial paleoclimate. For more information, please visit my website.

Environmental Geology
Course Description
Environmental Geology
Geological processes form the physical framework on which ecosystems operate. We require an understanding of the geological environment in order to minimize disruption of natural systems by human development and to avoid hazards such as floods and landslides. This course is an overview of basic tectonic, volcanic, and landscape-forming processes and systems, including earthquakes, rivers, soils, and groundwater. Environmental effects of energy, mineral, and water resource use, and waste disposal are also examined. Weekly field labs after spring break. Registration priority for first and second-year students. 3 hrs. lect./disc., 3 hrs. lab/field trips (formerly GEOL 0112)

Act Tectonics-Earthquake Haz
Course Description
Active Tectonics and Earthquake Hazards
In this class we will explore what drives Earth’s system of tectonic plates and why plate motion causes earthquakes. We will learn about modern techniques used to document plate motion and predict the size, style, and timing of earthquakes. Students will also explore the numerous hazards associated with earthquakes and how the threat they pose to humans can be mitigated. Learning goals will focus on reading primary scientific literature, identifying unanswered questions, and developing ideas for original research. (One introductory course in ECSC, or instructor’s permission) 3 hrs. lect. (formerly GEOL 0301)

Remote Sensing in Geoscience
Course Description
Remote Sensing in Environmental Science
In this course we will discuss fundamentals of air- and space-based remote sensing applied to geological and environmental problems. The core goal is to understand how different wavelengths of electromagnetic radiation interact with Earth's surface, and how images collected in these different wavelengths can be used to address questions in the Earth sciences. Lectures will present theory and basics of data collection as well as applications in hydrology, vegetation analysis, glaciology, tectonics, meteorology, oceanography, planetary exploration, and resource exploration. Labs will focus on commonly-used imagery and software to learn techniques for digital image processing, analysis and interpretation in Earth science. (one ECSC course, or by waiver) 3 hrs. lect., 3 hrs lab (formerly GEOL 0322)

Telling Time w/Geochronology
Course Description
Telling Time with Geochronology
In this course we will explore the field of geochronology: the methods by which the age of rocks and landforms are determined to illuminate the mysteries of ancient earth. Content will include understanding how rocks and landscapes form, as well as aspects of physical chemistry such as radioactive decay and mass spectrometry. Learning will occur through seminar-style discussions and hands-on lab work centered around a 4-week project using U-Pb dating to test hypotheses about the geologic history of Vermont. Students working in small groups will learn how to use instruments such as the scanning electron microscope and laser-ablation mass spectrometry. This course is nominally restricted to geology majors although other interested students are encouraged to contact the professor.

Shaping Earth: Past and Future
Course Description
Shaping Earth: Past and Future
This course will explore the fundamental processes that have shaped Earth and its atmosphere over time, including plate tectonics, glaciation, rivers, and soil-forming processes. Most scientific content will be presented in a series of place-based field trips to experience examples of these processes and better understand how scientists study them. Research, writing, and speaking skills will be developed through interactive exercises and a series of assignments, each one including multiple revision cycles.

Senior Thesis Research Seminar
Course Description
Senior Thesis Research Seminar
This seminar will focus on methods and strategies for completing advanced geological research and provides a springboard for senior thesis research. Topics will include field and laboratory techniques, primary literature review, and scientific writing. Students taking this course are expected to be simultaneously working on the early stages of their senior thesis research. During the semester students will present a thesis proposal and the seminar will culminate with each student completing a draft of the first chapter of their senior thesis. GEOL 0400 is required of all geology majors. 3 hrs. disc. or lab
