Research Interests

  • Biophotonics
  • Optical sensing
  • Instrumentation and measurement
  • Near-infrared spectroscopy

The focus is on agri-engineering and instrumentation for non-destructive evaluation of agricultural products. The work  covers the quality assessment of internal fruit properties (including its application to high speed fruit grading) and assessment of pasture, milk, meat, eggs, etc. The main techniques employed for sensor development are NIR spectroscopy and photon migration methods as well as nano-photonics and laser induced breakdown spectroscopy.
