I have been a hydrologist with the USGS New Jersey Water Science Center since 1993. My work relates primarily to groundwater systems, numerical modeling, estimating recharge, the use of artificial neural networks, and a variety of water-quality issues including those with detention basins.

I grew up and worked on the family farm until I changed course and earned a B.A. in geology from Franklin and Marshall College and an M.S. in geology from Miami University. Before USGS, I worked for several hydrogeologic consulting firms and spent six years with the New Jersey Geological Survey.
