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.
