[1][2] Currently professor of civil engineering at the University of Melbourne and professor of engineering at James Cook University, she has also advised numerous government and industry bodies in the United States and Australia and appeared widely in press, radio, television and website segments communicating her findings to the general public.

[20] Her nationally representative population studies found that 34.7% of adults in the US, 33.0% in Australia, 33.1% in Sweden, and 27.8% of people in the United Kingdom report adverse health effects from exposure to fragranced products.

[25] Adverse health effects include asthma attacks, breathing difficulties, migraine headaches, dizziness, seizures, rashes, and gastrointestinal problems.

[25] The effects are also economic with "more than 20% of respondents entering a business, but leaving as quickly as possible if they smell air fresheners or some fragranced product".

For instance, more than twice as many people would prefer that workplaces, health care facilities and professionals, hotels, and airplanes were fragrance-free rather than fragranced.
