Postdoctoral Researcher at Zhejiang University of Technology

πŸ‘‹ Hi, I am Gefei Zhang!

I am currently a postdoctoral researcher at Zhejiang University of Technology, working with Prof. Guodao Sun. My academic journey includes being a core member of the Data Visualization Group (ZjutVis) since 2020. I was also a visiting scholar at Texas A&M University, where I had the privilege of being part of the Dream Lab and working with Prof. Meng Xia.

My research lies at the intersection of Visual Analytics, Human-Computer Interaction, and Education Technology. Specifically, I focus on:

  • Visual Analytics: Developing interactive approaches for large-scale data analysis
  • Education Technology: Exploring the application of visual analytics in educational contexts

The overarching goal of my research is to bridge the gap between complex data analysis and intuitive understanding through innovative visualization approaches.

πŸ‘€ If you are interested in my research, please feel free to contact me via gefeizhang943 [at] gmail.com.

More information will be update soon~
