Education:

2012-2016, Bachelor of Science in environmental science, Nanjing Normal University

2016-2019, Master of Science in environmental science, Nanjing Normal University

Since 2019, PhD candidate in ecohydrology, Leibniz Institute of Freshwater Ecology and Inland Fisheries Berlin

 

PhD Topic

Tracer-aided monitoring and modelling of catchment-scale ecohydrological processes and its implication for water quality

 

Objectives

1.       Investigating the impacts of long-term hydroclimatic change and riparian management on hydrology and water chemistry in a mixed land use catchment, and identifying the hot spot area of the hydro-chemical functioning

2.       Exploring the hydrology, isotopes, water chemistry and vegetation phenology in a higher spatiotemporal resolution in a riparian peatland (the hot spot area)

3.       Quantifying the hydrological and water quality fluxes in both catchment and hot spot area using distributed hydrological/water quality modelling

 

Methods

Multiple approaches are used to realise the objectives, including:

1.       Dense field sampling of water isotopes, water quality indices

2.       Hydrological and water quality modelling (mHM-Nitrate, and EcH2O-iso for plot or catchment-scale modelling)

3.       Technologies of unmanned aerial vehicle (UAV) and geographic information system (GIS) for ultra-high resolution multispectral imagery and DEM

4.       Deep learning approach for vegetation classification and soil moisture estimation based on UAV imagery
