This week on IAQ Radio+ we welcome J. David Miller, PhD. back to IAQ Radio+ for a discussion on the newly revised AIHA Green Book "Recognition, Evaluation and Control of Indoor Mold" and an in depth discussion of mycotoxins. Dr. Miller received his secondary education at the University of New Brunswick, before studying at the University of Portsmouth in England, where he was also a NATO Science Postdoctoral Fellow. He began his post-university career at Agriculture Canada in 1982, and became head of the Fusarium mycotoxin program in 1988. He became a Professor & NSERC Research Chair at Carleton University in 2000. From 1999-2008, he was a visiting scientist and science advisor in the air health effects section of Health Canada. His work involves the development of methods to assess exposure to determinants of respiratory health in indoor environments and on fungal toxins in food and feed. Dr. Miller has published >350 papers on fungi and fungal toxins and has co-written 10 books on the public health aspects of exposures to fungi, and has several patents.
