Overview
Background
I completed my Bachelor of Pharmacy at Kings College London, followed by pre-registration and subsequent employment as a pharmacist with Boots the Chemists in Central London. With a PhD in plant biochemistry with Royal Holloway College, University of London, and the Royal Botanic Gardens, Kew, I moved first to Cornell University, USA and then The University of Western Australia for postdoctoral research. I moved to the School of Pharmacy at The University of Queensland in 2007.
Following a number of years in plant research, my current research interests generally link back to plants in some way. Many of my projects develop in response to requests for help from healthcare professionals, and so I have a strong focus on answering clinical questions using pharmaceutical science methods. See my research interests for more information.
I teach into the Bachelor of Pharmacy (Honours) in the areas of pharmaceutics, compounding and complementary medicines. I also teach the clinical drug development course for our Master of Pharmaceutical Industry Practice. I am currently the Director of Teaching, Learning and Student Experience for the School of Pharmacy. I have supervised 28 PhD students to completion, and over 60 undergraduate and masters independent research project students.

Non-cigarette sources of nicotine
• Electronic nicotine delivery devices have potential to reduce tobacco use among smokers. We are interested in the regulation of nicotine vaping devices as medicines in Australia, their safety and their effectiveness as a nicotine replacement therapy for smoking cessation. • Leaves from Australian species of Nicotiana are mixed with wood ash for chewing/sucking as a source of nicotine (commonly called pituri or mingkulpa) by some Australian Aboriginal people. We are interested in pituri use, and chemical components of the pituri plants. • While for most smokers it is the non-nicotine nasties in tobacco smoke that are the primary cause of detrimental health effects of smoking or chewing, the nicotine is also a problem for the babies, children and youth. We are investigating the influence of nicotine from all sources (e.g. vaping, pituri, patches, gums as well as smoking) during pregnancy on weight and health of babies.
-
Medication delivery
• People who cannot swallow tablets whole often cut or crush them. We apply the International Dysphagia Diet Standardisation Initiative (IDDSI) framework to assess swallowing safety of oral medicines. We are also investigating the effect of crushing and splitting tablets or capsules on drug delivery and bioavailability, particularly where the crushed tablets are mixed with liquids thickened with plant gums as these have the potential to delay drug dissolution. • Improving the treatment of xerostomia is being approached through considering approaches to saliva replacement, buccal delivery of pilocarpine, and information sources for pharmacies to assist with product selection.
-
Complementary medicines
Complementary Medicines are a large category of products sold within pharmacies that include herbal medicines, nutritional supplements, vitamins & minerals, homeopathy and aromatherapy. Evidence supporting their efficacy for claimed indications is variable, with some being strong while others are exceptionally weak or non-existent. We are involved in determining the extent and motivations for use, along with clinical trials to test the effectiveness of complementary medicines.
