My overall research interests are to understand coastal environments on transcending time scales in the Quaternary inclusive recent changes by human activities, from viewpoints of sediment budget/dispersal, depositional system development, and sequence stratigraphy particularly in relation to sea-level changes, and from a standpoint of human impacts.
Particularly interests include the modern and ancient formation of sedimentary strata in continental margin environments, with special foci on deltas.
