"Anything else you are interested in is not going to happen if you can't breathe the air and drink the water. Don't sit this one out. Do something. You are by accident of faith alive at an absolute critical moment in the history of our planet."

The focus of my research is to evaluate the effects of climate change on mountain lakes and to improve techniques used to interpret such changes. Understanding the response of high-elevation freshwater systems to climate change is critical for interpreting past environments and predicting the abundance of freshwater resources.
