Research interests:

Marine sedimentological processes include sediment fluxes, transport, accumulation, and geochemical interactions with the water column.
Timor’s current studies include; exploring sediment transport across the shore to deep sea continuum, biogenic and lithogenic fluxes through the water column,  the effects of biological resuspension in the marine environment, and the introduction of terrestrial sediments into the Gulf of Aqaba by desert flash floods, turbidity currents, post-deposition processes and dispersal of flood sediments in the sea.
