My research interests relate to how microbial processes influence wetland biogeochemical cycles. I’m particularly interested in linking “omics” tools with chemical biomarkers to better understand the microorganisms driving carbon and nutrient cycling in wetlands. My current research focuses on particulate organic matter and organic phosphorus dynamics within South Florida Stormwater Treatment Areas to minimize phosphorus loads to the Everglades. I am also investigating the fate of coastal peat when it’s exported into aquatic systems, and studying the effects of crab grazing on coastal salt marsh loss in the southeastern US.

I received my undergraduate degree from UC Davis, and my PhD from the University of Florida’s Soil and Water Sciences Department, and have studied systems ranging from coastal marshes to tropical peat domes.

Ph.D. Student

I received my undergraduate degrees in Biology and Religious Studies from the University of Mississippi. I am interested in studying the biogeochemical cycling within aquatic ecosystems such as wetlands, estuaries, or coastal systems. Specifically, my interests are related to the internal and external drivers that control nutrient cycling and the effects anthropogenic activities have had on these drivers. My upcoming project will employ the use of biomarker-based proxies  (including amino acids and stable isotopes for carbon and nitrogen) to identify the drivers of organic matter and phosphorus turnover in South Florida Storm Water Treatment Areas.

I received a Bachelor of Science in Geology, majoring in Lake Geochemistry, from Chulalongkorn University in Thailand. According to this background, I am fascinated in tracing series of changes in environmental properties that affected its inhabitants, from prehistoric date up to the present, as well as detecting what humankind has adulterated the pristine environment. My upcoming research includes the application of aquatic biomarkers in tracing biogeochemical changes in Mekong River Delta, Southeast Asia. My aspiration is to distinguish the anomalous anthropogenic forces from natural drivers, such as climatic variability, since both have been threatening this region for decades.
