Biographical details

Quan Hoang Nguyen is a post-doctoral researcher of InfoVis research group at the School of Information Technologies, Sydney University. He has gained rich experience in Software Engineering and R&D at various organizations.

*** Quan is currently looking for new opportunity ***

Current project: Working on Software visualization funded from an LP project with Prof. Peter Eades. Working with researchers from Oracle Labs led by Dr. Cristina Cifuentes. Investigating tools and techniques for program comprehension and bug tracing.

His research profile is available at https://www.researchgate.net/profile/Quan_Nguyen43.

Research interests

His research interests include Graph Visualization, InfoVis, Data Mining, Cloud Computing, Program Analysis, Compiler Optimization and Transactional Memory.

Current research highlights:

  • Software visualization: developing new metaphors and new system for software comprehension.
  • Proxy graph: I introduced the concept of proxy graphs and several metrics for big graphs. Proxy graphs are apparently useful for big graph visualization. (see "Proxy Graphs: Visual Quality Metrics for Big Graphs", IEEE PacificVis 2017).
  • Faithfulness: I introduced the concept of faithfulness of graph visualizations. This criterion is very relevant in the era of big graphs. I proposed three levels faithfulness: information, task and change faithfulness. (for details, see "On the faithfulness of graph visualizations", IEEE PacificVis 2013).
  • Stream graph: I proposed and implemented techniques for visual analysis of stream graphs. (see "Stream edge bundling", Graph Drawing 2013).
  • Edge bundling: I proposed and developed edge bundling frameworks to help visual analysis of large graphs.
