Below is a list of recent student presentations at national meetings that have come out of my research group. These can give you an idea about the type of projects we are working on.

• Red Tide in Tampa Bay: Fish Kills and Ammonium Enrichment Correlations.
• Surface Water Injection into the Floridan Aquifer: Biogeochemical Transformations and Ramifications.
• Development of a Microfluidic Reverse Flow Injection Analysis (rFIA) Method with Automatic Background Fluorescence Correction for the Detection of Nanomolar Concentrations of Ammonium in Natural Waters.
• Characterization of Naturally Occurring Carbon in Lake Okeechobee Water and its Compositional Change Following Recharge and Storage in the Upper Floridan Aquifer.
• Tampa Bay Ocean Acidification and the Influence of Dissolved Organic Carbon on Accurate Carbonate System Measurements.
• Total Alkalinity Trends and Troubles in Tampa Bay
• Primary production is greener on the other side: Influence of hurricanes on the West Florida shelf

My primary focus when working with research students is to mentor them in the analytical methods of nutrient analysis, automated instrumentation and data visualization. The experiences gained participating in this research give students a competitive advantage when applying to graduate programs due to their exposure to advanced techniques and inclusion in the publication and presentation process. A priority is placed on the development of scientific communication skills. Students are involved in all stages of the proposal and manuscript preparation and submission, and these experiences enhance student development as both scientists and leaders.
