Ice is an integral part of the Earth's climate system. To anticipate potentially disruptive effects on climate and sea level, we need to understand how and why ice sheets change. In the Ice & Climate Group at Georgia Tech, we are seeking to develop new and innovative ways to understand changing ice sheets and their complex interactions with the climate system. Our work is guided by a fundamental curiosity and passion to explain the world that we live in.

In our group, we use math, high-performance computing, and data (big, medium and small in size). We develop models, from simple to complex, in order to explain the changes we observe and to simulate those that may occur in the future. We use ideas from dynamical systems theory, statistical mechanics, condensed matter physics, and scientific computing to study the cryosphere. We also work with a talented cast of collaborators who work on, within, and under ice sheets and use state-of-the-art platforms such as satellites, aircraft, and drones to measure ice sheet changes.
