Research

My research seeks to explain how the Earth's surface is influenced by changes in climate and human activities over diverse timescales. Nearly all of my studies involve directly measuring properties of the Earth's surface and trying to understand how those properties are created by climatic, geologic, and anthropogenic processes. My research group collects data using a very wide range of techniques, including sophisticated laser mapping systems, remotely sensed imagery, and less sophisticated but useful field methods that include traditional instrument surveys. The basic research questions I address can be posed in many different settings. As a result, my publications encompass a wide spectrum of surficial environments including glaciers, beaches, river channels, and earthworks, in addition to publications that investigate changes in climatic processes such as temperature patterns and heat stress caused by landcover change.
