I have worked on a wide range of natural resource problems, including:
- mineralogy and transport of naturally occurring radionuclides in groundwater, Newark Basin, New Jersey;
- generation of natural gas, diagenetic process, and prediction of hydraulic properties of natural gas and petroleum reservoirs by mechanical and geochemical processes, Piceance Basin, Colorado, and Mid-Norway Basin, North Sea; and
- saltwater intrusion and the effects of climate change on groundwater resources in coastal Georgia and South Carolina, and in southeastern coastal Florida.
I currently supervise scientists and provide technical oversight on a wide range of hydrologic studies of significant relevance to water resources in South Florida.
Science and Products
Effects of hydrologic system alterations on salinity in the Biscayne aquifer in Broward Co.
To address concerns about the effects of water-resource management practices and rising sea level on saltwater intrusion, the U.S. Geological Survey in cooperation with the Broward County Environmental Planning and Community Resilience Division, initiated a study to examine causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system on salinity distribution...

Drought Conditions in Puerto Rico
A drought is a period of drier-than-normal conditions that results in water-related problems. When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.
Climate of Puerto Rico
In general, the east-west trending Cordillera Central and Sierra de Cayey mountains form an insular hydrologic divide that separates the island of Puerto Rico into two climatologically distinct regions. The northern two-thirds of the island has a relatively humid climate whereas the southern one-third of the island is semi-arid.
