Brief Bio/background and silica work

I have a MSPH (1977) and PhD (1983) from University of North Carolina, Chapel Hill. I have been interested in silica, silicosis and cancer most of my career and I organized three international symposia addressing these issues in 1984, 1993 and 2002. Early in my academic life I challenged the occupational medicine dogma by arguing that silica dust exposure was linked to pulmonary cancer.  Furthermore, I argued that silica was a multi-potential toxin and was a cause of auto-immune diseases, kidney ailments, nonsilicosis respiratory diseases (including TB), and that risk assessment methods could be used to determine safe levels of ambient silica exposure.  These associations were built on three foundations showing increased lung cancer after silica dust exposure, after diagnosis of silicosis, and in inhalation studies of laboratory animals. I served on the initial assessment by the International Agency for Research on Cancer (IARC) of silica dust in 1986.

Brief Bio/background and silica work

I am a Respiratory Physician from Melbourne, Australia. I undertook a fellowship in occupational lung diseases in 2007 at the University of Toronto, Canada and have a Master’s Degree in Occupational and Environmental Health from Monash University (2009). I am a Senior Research Fellow at the School of Public Health and Preventive Medicine, Monash University and lead physician for the Alfred Hospital’s Occupational Respiratory Clinic. My research interests include work-related asthma, laryngeal (vocal) cord dysfunction, and the emergence of silicosis affecting stone benchtop workers.

 

I was lead author of the paper “Artificial stone-associated silicosis: a rapidly emerging occupational lung disease. Occup Environ Med. 2018” which drew attention to the urgent issue of accelerated silicosis in the stone benchtop industry occurring in Australia. Increased awareness of silicosis in this industry has led to government responses including a ban on dry cutting of artificial stone, establishment of worker health assessment programs and a silica-associated disease registry in Victoria, which I am the Chief Investigator.

I am an occupational hygienist and exposure scientist. The focus of my research is the evaluation of workplace exposures to better understand the causes of occupational illness and how to best prevent them. I have examined silica exposure in mining using historical databases as well as new measurements of contemporary exposure. More recently I have been working with administrative health data to examine trends in silicosis incidence for the province of Ontario, Canada.
