    Research Interests

    Investigation of the main pathways in marine ecosystems; development of coupled physical-biological models.

    Current Research

    Use of data-assimilative models in conjunction with observations from long-term time series and Ocean Color data (such as SeaWiFS and MODIS) to modify model pathways and estimate model parameters and errors for the North Pacific carbon cycle; modeling of ecosystem response to upwelling off the Oregon coast; data-assimilative modeling of eutrophication in the North Sea.
