Dr. Hongbing Sun received his doctorate from Florida State University in 1995, specializing in coastal hydrology, and currently holds the rank of Professor of Geological and Environmental Sciences. Prior to joining the Rider faculty in 1997, Hongbing was an Assistant Professor of Geology at Temple University. His research has focused on the interaction of groundwater and ocean tides along the New Jersey Coast, estuary dynamics of Apalachicola Bay, Florida, and the effect of the fluctuation of water level on gasoline contamination in New Jersey aquifers. More recently, Hongbing has begun examining the tidal effect on the borehole fluid and temperature change in the deep-ocean sediments of the Juan de Fuca Ridge, eastern Pacific Ocean, and the environmental impacts of development in the Delaware River Basin, particularly processes controlling salt and ion migration through the watershed. Finally, Hongbing continues as a member of a research team, funded by the Edwin B. Forsythe Wildlife Refuge in Brigantine, NJ, investigating the control of phragmites through tidal inudation at the Refuge.
