I’m an ecosystem ecologist and have a broad interest in how native vegetation influences nutrient cycles, especially in the lowland tropics. I find it fascinating that lowland forests can maintain such high levels of biomass with such low levels of phosphorus availability. I’m interested in contributing to our understanding of how these native systems can be so productive. This line of research is important for understanding how nutrient cycles, and therefore productivity, change with land conversion to pasture, agriculture, plantations and secondary forest.

For my dissertation I’m researching the role of dissolved organic carbon and organic acids on plant phosphorus availability in lowland tropical forests. At the moment I’m most interested in how leachate from leaf litter may increase phosphorus availability. I also hope to investigate the role of organic acids from root exudates on plant phosphorus availability.

I’m a PhD student at University of Florida in the School of Natural Resources and Environment. I am a student in Dr. Michelle Mack’s lab in the UF Botany department and I will be working with Dr. Turner’s lab at STRI.
