Welcome to

Marine-Coastal Sedimentology Lab



We are recruiting prospective master & PhD students.
​Join us in exploring extreme tidal environments.


Professor Kyungsik Choi, a.k.a. tidalchoi, has devoted entire his academic career to the sedimentological and morphodynamic characterization of the tide-influenced depositional systems in various settings to better predict spatio-temporal variability of facies and stratigraphic architecture, to evalute natural and anthropogenic impacts on the depositional systems, and to reconstruct the evolution of the depositional systems. 



Marine and Coastal Sedimentology Lab focuses on various issues related to sedimentary processes and morphodynamics of estuaries and deltas spanning from tropical to arctic setting around the globe.
