Greg Tucker Group

The Computational Geomorphology Group studies the processes that shape the Earth's surface. As the 18th century founders of geology recognized, our planet's surface is continually sculpted by processes that obey the basic laws of physics and chemistry. Most of these processes can be seen in action on today's Earth. We focus on discovering how the physics of processes like floods and landslides interact to shape the land surface, drive mass and energy across it, and determine how a landscape will respond to forcing from the atmosphere above and the solid earth below. We also develop software tools to enable computational modeling of earth-surface processes.

My interests lie in geomorphology and landscape evolution. My group seeks to understand the physics of diverse geomorphic processes, and how these processes interact to shape terrain and move sediment.
