Faculty & Research Scientists
|David K Arctur|
Geographic Information Systems and Database Management Systems, with focus of interest in standards for interoperability of data and models for multidisciplinary geosciences research (water resources, climate, and geohazards in particular). Data and model semantics, and digital preservation of physical samples are crosscutting subthemes of interest.
|Jay L Banner|
Isotopic methods, groundwater, oceans, ancient oceans, climate change, aquifers, caves, environmental science, geochemistry, paleoclimatology
Dr. Caldwell is a hydrologist and geoscientist specializing in field investigations and numerical modeling associated with near-surface vadose zone hydrology, landscape evolution, and soil moisture/ET. His current research focuses on ecohydrology, soil moisture modeling and monitoring, restoration and characterization of disturbed lands, the characterization and scaling of soils and hydraulic parameters, near-surface geophysics, and parameter optimization and numerical methods.
|M Bayani Cardenas|
Hydrology and Hydrogeology
|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.
