Research Interests

I study the Earth's recent geological history (the Quaternary period). My research focuses on changes of past climate by examining sediments deposited in lakes and rivers and by glaciers.  A major effort has been studying glacial Lake Agassiz, once the world's largest lake, and what impact its overflow had on continental and ocean systems and on global climate change.  I also study lakes in arid regions.  My research has been done on every continent.
