P. Dreux Chappell

P. Dreux Chappell is an Associate Professor at the University of South Florida College of Marine Science, specializing in interdisciplinary research at the intersection of phytoplankton physiology and ocean chemistry. He is affiliated with the BIOME Lab, where he conducts cutting-edge research using molecular tools and biogeochemical analyses.

• Education: BA in Biology, PhD in Chemical Oceanography

Chappell's research focuses on Marine Microbial Ecology and Trace Metal Biogeochemistry, particularly how nutrient forms (iron, phosphorus, nitrogen) influence phytoplankton community composition and biogeochemical modeling. His work spans coastal and open ocean environments, from the Pole to Pole, with emphasis on nutrient limitation and quantitative molecular techniques.

The 15 most recent articles highlight trends in Nitrogen Fixation, Trace Metal Cycling, and phytoplankton community dynamics, often leveraging Radium isotopes, dual nitrate isotopes, and metatranscriptomics to study nutrient sources, microbial interactions, and oceanographic processes across diverse regions like the West Florida Shelf, Mid-Atlantic Bight, and Arctic Ocean.
