PhD student; Research associate

Dynamics of ground- and surfacewater quality caused by intensive land subsidence, climate- and landuse changes in the southern Mekong Delta, Vietnam

Research interests

I am interested in various environmental systems, their geochemical characteristics, and their interaction with each other. Currently I am working on water-related environmental challanges in the Vietnamese Mekong Delta with an emphasis on coastal groundwater quality and its potential salinization due to seawater intrusion. The confined, multi-layer aquifer system is complex, and many factors determine the groundwater composition, e.g., salinization and freshening processes, redox reactions, dissolution of minerals as well as anthropogenic influences.

My research is part of the project ViWaT - Engineering
