Welcome to My GitHub. πŸ‘‹

I'm YoungDon Choi, a principal researcher at K-water AI research Lab ( https://github.com/Kwater-AILab) . I have worked at K-water (https://www.kwater.or.kr/eng/about/sub02/kwaterPage.do?s_mid=1099) since 2003 with many experiences such as dam operation, water resources survey and planning, water technology strategy, and water information system. Currently, I'm working at K-water AI research Lab to apply AI in water resources fields.

I did my PhD from 2017 to 2021 at the UVA Hydroinformatics research group (https://uvahydroinformatics.org/team/) in University of Virginia (https://www.virginia.edu/). This is my Dissertation (https://doi.org/10.18130/g9tg-0c69), google scholar(https://scholar.google.com/citations?user=VCyCE5QAAAAJ&hl=en) and Resume(https://github.com/DavidChoi76/profile/blob/main/YD_Choi_17June2022.pdf)

These are my current research. πŸ€“ Focusing πŸ€”

  1. πŸ”­ Application of neuralhydrology and other AI technologies for upstream and downstream analysis for dam operation
  1. 🌱 Long-Term Water Demand Forecasting

  2. πŸ‘― Satellite Rainfall Distribution using Machine Learning

  3. πŸ”­ Urban Inundation Forecasting using Machine Learning as Surrogate Model

  4. 🌱 Application of NeRF and 3DGS in Water Infrastructures

  5. πŸ‘― Drought Quantification using Social data such as Newspapers
