About Megan


I am currently researching honey from all around the world. If you have honey collected from one apiary site and would be interested in sharing this with me, please get in contact and I can provide more information.

Research Interests

I have a strong Analytical Chemistry background, having worked in a number of research projects and with various instruments.

My research is often industry based to help New Zealand companies solve problems.

I am interested in many areas of honey analysis - with a large focus on mānuka honey. I am currently expanding into honey bee  and pollen research.

I am also interested in trace element and heavy metal analysis in food and the environment.

Current research topics include:

  • Mānuka honey (including kinetics of conversion of DHA to MG)
  • Nectar analysis
  • Glass analysis for forensic purposes
  • Trace element analysis (including water, honey, bees)
  • Novel compound isolation
  • Detection of volatile compounds

Instrumental Techniques of interest:

  • HPLC (UV, RI, Fluorescence detection)
  • ICP-MS
  • Laser Ablation ICP-MS for spatial imaging
  • GC-MS
