Main areas of research

I'm involved in a wide variety of research. These can be roughly grouped as follows:

  • 3D microscopy image visualisation and analysis
  • Virtual Reality applications
  • Machine learning with a focus on deep neural networks applied to image processing problems
    • Human Pose-Estimation
    • Face Recognition
  • Internet of Things (IoT) applications
