Research interests:
Marine sedimentological processes include sediment fluxes, transport, accumulation, and geochemical interactions with the water column.
Timor’s current studies exploring: biogenic and lithogenic sediment transport across the shore to deep sea continuum, particle fluxes down the water column, turbidity currents from rivers and in submarine canyons Terrestrial sediments discharge of into the Gulf of Aqaba from desert flash floods and post-deposition processes. biological resuspension and the marine silica cycle.
