Job experiences

HKU HK PolyU

As trained as a multidisciplinary engineer, I am trying to solve complicated problems in building and construction with computational intelligence:

  • 🏙 Building/city informatics: automatic BIM/CIM modeling, digital twin, blockchain, 2D-3D semantics, voxel, geo-data, visual object detection,
  • 📈 Optimization algorithm: derivative-free optimization (DFO), hyper-heuristics, combinatorial optimization, multi-agent system, NK-modeling,
  • 📡 Urban sensing: LiDAR, VR/AR, IoT, RFID, NFC, phone sensors, GPR, Arduino,
  • 🤖 Machine learning: prediction, big data analytics, pattern recognition, text mining, semantics analysis, and
  • 🏗 Professional software: plugins (Revit, SketchUp), desktop solutions (C/C++, Java/EE, Python, Ruby, C#), web apps (JSP, HTML5, PHP), & DB (MySQL, Oracle, SQL Server, SQLite)
