Main Responsibilities：

• Participated in the soil and water conservation planning: earthwork calculation, introduction to the planning basis (regulations, technical standards, etc.) and project area (natural conditions, socioeconomic situation, soil and water loss and conservation) in the project.
• Prepared materials for submission to granting agencies and foundations
• Managed and responded to project related email, prepared, maintained and updated website materials
• Attended project meetings and area seminars, summarized results and prepared reports, presentations and other materials.
• Performed miscellaneous job-related duties as assigned

Developing watershed management strategies to reduce non-point source pollution

• Conceptualized the research and developed the theoretical framework
• Designed 60 Best Management Practice (BMP) scenarios and developed a database for watershed management
• Developed a simulation-based optimization framework to search cost-effective watershed management strategies and compared the performance of several advanced MOEAs applied to a real-world muli-objective optimization problem. The average cost of optimized strategies is 32.22% or 47.83% of the commonly used strategies
• Delivered a presentation on non-point source pollution studies and watershed management to international graduate students (2022-5-16)
• First-authored the research manuscript, which was published

Assessment of influencing factors on non-point source pollution critical source areas

• Conceptualized the research and developed the theoretical framework
• Collected spatial and attribute data of the study watershed (runoff, soil property, land use and meteorological data, etc.), applied a semi-distributed model (AnnAGNPS) to identify the critical source areas
• Applied machine learning technique to identify the dominant influencing factors of critical source areas, explored the non-linear relationships and potential thresholds that may cause great changes in pollution losses
• Filtered a set of suitable BMPs to reduce non-point source pollution for decision makers
• First-authored the research manuscript, which was published

Research on quantifying the effectiveness of vegetated buffer stripes

• Assembled experiment apparatus, cultivated vegetation and collected water samples in the field experiments, measured water quality in the laboratory
• Quantified the reduction rate of vegetated buffers on sediment, total nitrogen and total phosphorus, identified the optimal width of stripe and vegetation type for non-point source pollution reduction in the Three Gorges Reservoir Region
• Co-authored the research manuscript, which was published
• Co-designed a technique for constructing vegetated buffer stripes in sloping areas, which was published as a patent

Analysis of runoff and sediment variations in the Three Gorges Reservoir Region

• Conceptualized the research and developed the theoretical framework
• Analyzed long-term (2002-2017) runoff and sediment loads changes in the Three Gorges Reservoir Region using Mann-Kendall test and Double Cumulative Curve
• Quantified the impact of human activity and climate change on runoff and sediment
• First-authored the research manuscript, which was published

Responsibilities：

• Supervised 6 undergraduate students on their research project. This study focuses on developing an efficient software to filter practical BMPs to reduce non-point source pollution, and to calculate their construction costs for decision makers
• Made presentations on remote sensing and hydrological & water quality modeling
• Prepared and revised the application materials, made the presentation for final defense
• Co-developed the BMPs selection system software, which was registered and licensed

Responsibilities：

• Conceptualized the research and developed the framework
• Designed the research project. This study focuses on exploring the effectivenss of different vegetation patterns on soil erosion in sloping areas
• Drafted and revised the application materials, delivered a presentation and raised funding (5k RMB) for the project
• Designed experiments, assembled experiment setups (cultivated grass on a soil-bed experimental flume), collected sediment samples and measured sediment loads
• Wrote the experimental report, drafted research manuscripts, and made the final defense
