Research Overview
'My research focuses on assessing the biogeochemical role of various particle processes such as particle formation, sinking, lateral transport and remineralization. These processes have important implications for regional and global carbon budgets, the manifestation of ocean acidification, the supply of organic material to subsurface ecosystems, the balance of carbon dioxide between the ocean and the atmosphere, and the distribution of carbon, nutrients and trace elements throughout the oceans and sediments.

To address these research topics, my laboratory utilizes and develops a variety of oceanographic sampling and analysis techniques including bulk sediment traps, polyacrylamide gel traps, in situ photography, particle filtration, and in situ particle incubations. These tools enable the assessment of the magnitude and composition of particle fluxes and composition, the particle size distribution, the average sinking velocities of particles in the water column, and the rates of particle decomposition through microbial respiration.

In addition to this oceanographic observational work, I also use numerical models of ocean circulation and biogeochemistry to investigate the combined effects of particle export, sinking, lateral transport, and remineralization.
