Jack is a Lecturer in Pharmacy and Pharmacology. He completed both a Bachelor of Pharmacy (Honours) and a Doctor of Philosophy at UniSA. Jack is a practicing Pharmacist and has worked in several pharmacies spanning across rural Victoria and urban and rural South Australia. He is credentialed to provide Home Medicine Reviews and Residential Medication Management Reviews and is also a vaccinating and prescribing pharmacist. 
Jack has a strong interest in improving medication safety which is evident in his clinical practice, research and education of future health professionals. Maintaining clinical practice allows him to draw on real world experiences and incorporate this into his contemporary teaching and research endeavours. 
At UniSA Jack currently coordinates several courses including Fundamentals of Pharmacology, Pharmacy Practice Health Services Provision, Managing and Developing Pharmacy Operations, and Pharmacy Healthcare Services. He also teaches into other Pharmacy Practice courses across all year levels.
Jack is a member of the Quality Use of Medicines and Pharmacy Research Centre (QUMPRC) at UniSA. Jack's research focuses on integrating methodologies to understand how adverse drug events happen at both a molecular-level and also at a population-level. To do this he uses molecular modelling strategies to predict how drugs may interact with a particular target and then uses big real-world data to investigate the risk of adverse events at the population-level. Jack also has a strong interest in researching medicine utilisation. In particular his research focuses on understanding sequential treatment patterns and understanding the complexities of medicine utilisation during shortages.
Jack's commitment to understanding and minimising adverse drug events extends beyond UniSA. He is a member of the Local Advisory Committee for Pharmaceutical Defence Limited, a not-for-profit organisation which support pharmacists with risk management advice. 
Jack and his colleague Wern Chai (a/n Brian Chia) host a pharmacology educational instagram page where they post pharmacology related content. You can follow them by searching for "jbpharmacology".

The broad focus of my research is on understanding and improving the safe and effective use of medicines in real-world settings. My work integrates clinical practice, pharmacoepidemiology, and pharmacovigilance with data science and molecular modelling to better understand why and how adverse drug events occur. I have a particular interest in connecting foundational pharmacological mechanisms with population-level medicine use and outcomes.

Pharmacoepidemiology and Medicine Safety

Pharmacoepidemiology applies epidemiological methods to the study of medicines in large populations, providing insights into medicine utilisation, effectiveness, and safety in real-world clinical practice. My research uses large administrative and dispensing datasets to identify patterns of medicine use, quantify risks associated with medicine exposure, and evaluate the impact of regulatory or policy changes. A major focus of my work is understanding how medicine shortages, down-scheduling, and new models of pharmacist-led care influence patient outcomes and health system performance.

Pharmacovigilance and Adverse Drug Events

Pharmacovigilance focuses on detecting, assessing, and preventing adverse drug events (ADEs). My work explores innovative methods for ADE detection, combining big data analytics with molecular modelling to bridge the gap between clinical observations and biological mechanisms. 

By combining pharmacoepidemiological analyses with structural and systems pharmacology approaches, I aim to better understand how drug mechanisms translate into clinical and population-level outcomes. My work also extends to professional and health service research, investigating how pharmacists can apply these insights in practice to reduce risk, optimise medicine use, and improve patient care.
