About David N Leach

Associate Professor David N Leach
BSc(Hons)(La Trobe) PhD(La Trobe) MRACI CChem
David N Leach has over twenty years experience in phytochemistry specialising in chemical analysis and biological activity of essential oils. Much of the early work in this field was academic in nature and focussed on tea tree oil, its chemistry and antimicrobial activity.
Over the past six years his work has been more commercially focussed with a strong emphasis on application of essential oils as pesticides. Fundamental chemistry conducted at Australian Phytochemicals Ltd led to the development of a patent for BioProspect Ltd on QCIDE, a specific Eucalyptus oil based on the general class of chemical compounds referred to as B-triketones. Based on other work also undertaken at APL an additional patent has also been lodged for a termiticide utilising another endemic Australian essential oil.
His major areas of expertise lie in extraction and analysis of bioactive plant extracts using modern chromatographic techniques, mass spectrometry and NMR. He has published over 70 papers that reflect a broad range of chemical experience, is a member of CH21 Essential Oils for Australian Standards Association and has supervised or co-supervised 13 PhD students and 2 MSc candidates.
