Education & career


Research Fellow, School of Geography and Environmental Sciences, University of Southampton (2022-present)

  • Funded by The Leverhulme Trust, key role is to perform in-depth research on the state of the current anthropogenic impact on the global coastal floodplain.
  • Quantitative analysis of coastal environmental data, with Python and/or R
  • Disseminate findings by taking the lead in preparing publication materials for referred journals, presenting results at conferences, or exhibiting work at other appropriate events

Research Associate, State Key Laboratory of Estuarine and Coastal Research, Shanghai, China (2020-2022)

  • Built advanced geospatial and cloud computing methods to map long term coastal change and habitat loss due to land reclamation in major cities worldwide.
  • Analysis of remote sensing and GIS data along with machine learning application for coastal conservation
  • Successful accomplishment of research objectives within funding timelines
  • Publishing of scientific papers in peer-reviewed journals to support the research program
  • Regular attendance and presenting of results at national and international meetings to disseminate and promote the research

 Code for Climate, Shanghai (2020-2021) - Public workshops on making cities resilient to climate change

·        Partnered with Le Wagon and Green Initiatives, Shanghai to deliver capacity-building workshops on getting started with Python for geospatial analysis.  (Geopandas, Numpy, OSMNX, Rasterio etc)

·        Workshop on JavaScript for Google Earth Engine application in long-term vegetation and rainfall changes.

Ph.D. Research, School of Geographic Sciences, East China Normal University (2016-2020)

  • Understanding the spatial patterns of urban expansion at the coast.
  • Building high resolution map data of reclaimed land and features using Drone imagery
  • Mapping spatial patterns and trends of coastal land reclamation at 3 levels viz global, regional and national scales.
  • Application of automatic and adaptive thresholding methods for mapping long term coastline changes
  • Gaining expertise in a broad range of big data and remote sensing application

Research Trainee. Department of Environmental and Geographical Sciences (EGS), University of Cape Town, South Africa. (2018)

  • Fieldwork on sediments coring in semi-arid regions of Southern Africa
  • Delivered workshop on “Getting started with Google Earth Engine”
  • Participated in 2018 Macalester-Promona-Swarthmore Consortium Field Excursion to Kalahari Trans-boundary national park.
  • Assisted with pre-field work planning by building a GIS-based decision making support system for sediment coring in the estuarine region.
