Research Interests:
I am a geoscientist using a combination of tree ring and lake sediment climate indicators to reconstruct 1000 to 2000 years of climate history in the San Juan Mountains in southern Colorado. The goal of this research is to understand the nature of summer precipitation in the Southwest. My research has confirmed the existence of a multi-decade drought period in the second century A.D. The findings give evidence that extended periods of aridity have occurred at intervals throughout our past.
