Patterns and consequences of past climatic change: tracking the availability of water.

Water is a vital resource. Water affects vegetation, natural processes like wildfire, and human society. Availability of water, however, changes constantly because of climatic factors. Future conditions, like those of the past, will deviate from modern norms. Yet, we know little about the potential for change beyond that experienced in recent centuries. Ongoing work focuses on documenting and mapping changes in the levels of lakes throughout North America over the past 15,000 years. Through comparison with vegetation and fire history data, geochemical data, archeological data, and climate model simulations, the results demonstrate patterns of climatic variation and attendant impacts on landscapes and societies.

Teaching Statement

My training has been interdisciplinary, linking climatology and ecology with geology, and I have enjoyed teaching classes that span a wide range of environmental systems. Having attended Colorado College and Brown University, where undergraduate education was emphasized, I see its value and am committed to excellent undergraduate instruction. I also seek to be a dedicated advisor for graduate students. I am excited to organize seminars and courses with the aim of developing new ideas and advancing research, as well as teaching fundamental concepts about Earth System science, environmental change, and the scientific process.

In addition to training a diverse group of students, my research is integrated into a unique educational-outreach project focused on environmental change along the Continental Divide National Scenic Trail.
