Current Research Activities

Biological Systems and Organisms

My research activities have focused on the phytoplankton ecology with emphasis on harmful species, and the retrospective analysis of harmful algal blooms (through the study of dinoflagellate cysts) in the sedimentary record of coastal environments and its relationship with climate variability and human activities
