Kelly's PhD projects are focused on the use of radiolarians (unicellular, eukaryotic marine microzooplankton with siliceous skeletons) recovered from seafloor sediment and the water column, respectively, to:
i. reconstruct palaeoclimatic/palaeoceanographic parameters at various latitudes in the Southern Ocean using radiolarian abundance and composition data;
ii. quantify the contribution of radiolarians to the oceanic silica cycle.
