These include the Indoor Air Quality SIG of the Clean Air Society of Australia and New Zealand (CASANZ). He maintains current professional contact with advances in the industry and relevant science.

David has presented and published research papers and posters both nationally and internationally, including an extensive submission to the Australian Parliament’s Inquiry into Biotoxin-Related Illness in Australia. This submission was co-authored with Dr Richie Shoemaker, who is regarded as the world’s leading authority on Chronic Inflammatory Response Syndrome (CIRS).
