Biography

Thank you for your interest.  I am a graduate of the Western Sydney University Environmental Health degree program (Hons) in 2004, after which I went on to work for ACT Health as a Public Health Officer, before completing a Ph.D. in Occupational Hygiene and Environmental Health monitoring the impact of smoking bans on indoor and outdoor air quality in pubs and clubs under the supervision of Associate Professor Sue Reed FAIOH CIH COH.  I've worked as a consultant in occupational hygiene and environmental health, before moving to Colorado State University (IHCAHS NIOSH Centre for Agricultural Health and Safety) to undertake Post Doctoral studies measuring biological aerosol exposure and metagenomics of agricultural aerosols, as well as their health impacts on agricultural workers (respiratory function, immune response, gene by environment interactions) and working with in vitro models to study the proinflammatory effects of biological aerosols.  I've been working in the field of biological aerosols and biotoxins for over 15 years, and current research includes studying the toxicology of organic dust (mainly cannabis) and artificial stone dust using air-liquid interface (ALI) models with primary bronchial cells, as well as occupational and environmental monitoring for workers, workplaces and public exposures to aerosols such as silica, bushfire smoke, hemp dust, solvents, and noise. 

I also hold an adjunct Senior Lecturer position with Edith Cowan University, collaborating in occupational hygiene research projects and supervising higher degree research students.  I'm a  full member of the Australian Institute of Occupational Hygienists, Thoracic Society Australia and New Zealand, Environmental Health Australia, and International Society for Exposure Science, as well as current AIOH representative on the Department of Health's Biotoxin related illness committee, and peer reviewer for a variety of environmental health and occupational hygiene journals.

Respirable Crystalline Silica Exposure in the Engineered Stone Industry in Collaboration with Edith Cowan University, TestSafe NSW

An outbreak of accelerated silicosis has been documented in the global engineered stone industry.  There is no cure for this disease, and prevention is the only cure.  Western Sydney University in conjunction with TestSafe NSW and Edith Cowan University are currently investigating exposure to respirable crystalline silica, solvents and noise in the engineered stone industry, and assessment of controls to reduce worker exposure to potentially hazardous substances.  

From Farm to Pharmacy: Occupational Health and Safety in the Australian Marijuana Industry-2016 ongoing- in collaboration with Edith Cowan UniversityRole: Co PI

In February 2016 the Narcotic Drugs Act 1967 was amended to enable the lawful cultivation and manufacture of medicinal cannabis products. Cannabis was a Schedule 9 prohibited substance under the Australian Therapeutic Good (TGA) Administration’s Standard for the Uniform Scheduling of Medicine and Poisons (SUSMP) with limited exceptions.  However, the restrictions on its use have been changed to allow for the limited production medicinal grade cannabis for research in Australia.   Worker health and safety relating to the rapidly developing field of medical cannabis has primarily been focused on its potential use workplace (Phillips et al., 2015), and there is limited knowledge regarding the health and safety issues associated with cultivation, processing and manufacture of medicinal cannabis.  The aim of this project is to anticipate and evaluate potential health and safety hazards associated with the cultivation and manufacture of cannabis-based medicinal, dietary, textile and construction products to aid the emergent Australian cannabis industry in the development of best practice guidelines for workplace health and safety.
