  • My research interest is Florida’s karst hydrogeology focusing on water quality/quantity and flow dynamics in the Floridan aquifer system.  Springs have been a lifelong interest and restoration of these resources are paramount to Florida’s ecology and it economy.  At GFDI, I hope to mentor and fund students to increase our collective knowledge of the Floridan aquifer system through collaborations within and outside of FSU.
