Faculty & Research Scientists
|Daniel O Breecker|
The Breecker Group studies biogeochemical processes occurring at or near the land surface. We study soils and paleosols, caves and stalagmites, and other materials, such as volcanic glass, that give us insight into ancient Earth. We study timescales ranging from seasonal cycles to hundreds of millions of years. We use observations, mathematical models and both laboratory and field-based experiments to address an evolving range of questions. To learn more about the research we are doing, ...
Ice sheet mass balance, ice dynamics, subglacial hydrology, ice sheet stratigraphy, radar, GPS methods, uncertainty in ice sheet response to climate.
|Ian J Duncan|
Expertise in geomechanic and geochemistry applied to: risks associated with CO2 sequestration; hydraulic fracturing for shale gas production; environmental impact of hydraulic fracturing; and the water-energy nexus. Current research focuses on the scientific, environmental and public policy aspects of unconventional natural gas production, the water-energy nexus, and carbon capture and storage. He has a particular interest in risk analysis, decision making, and legal/regulatory issues related to fracing, CO2 sequestration, CO2-EOR, and energy production.

Dr. Yang's primary research interest is to understand the exchanges of momentum, radiation, heat, water, carbon dioxide, and other materials between the atmosphere and the Earth surface spanning from small (short) to very large (long) scales. This includes analysis of in-situ and remotely-sensed data for the Earth's surface, and modeling studies of weather, climate and hydrology at local, regional and global scales.
