My research interests involve studying regional to global biogeochemical cycles focusing on benthic-pelagic coupling of carbon and nutrients, through modeling and observations.
Currently, for my postdoctoral project, I am working on developing mechanistic model of benthic biogeochemistry to be integrated into Earth System Models (ESM). This is particularly a need of the hour, as several climate change mitigation strategies propose the use of seafloor to capture CO2 (or equivalents) through C sequestration in the sediments. And therefore, to understand the fate of this storage and quantify its efficacy, model experiments in ESM with dedicated sediment module is necessary before widescale deployment of these CDR techniques.
For my doctoral studies I focused on studying benthic-pelagic nutrient cycling in a seasonally hypoxic fjord in Northwest Atlantic. It involved studying water column time series, seasonal field works in the fjord basin, lab based experiments and analysis, and developing water column and sediment biogeochemincal models.
