Biographical details

Dr Patricia Tang has a PhD degree from Chemical Engineering, the University of Sydney, and a bachelor’s degree from Chemical Engineering, the University of New South Wales. She completed her PhD (title: The Relationship between Flow Fractal Dimension and Sedimentation Rate in Water Pollution Control) under the supervision of Professor Judy Raper. She commenced working full-time as a postdoctoral fellow in Aerosol Drug Delivery Group, led by Professor Hak-Kim Chan, straight after she completed her PhD in 2002.

Research interests

Dr Tang has extensive skills in characterisation of particles, including: dispersibility of drug powders using various impaction methods; determination of surface and mass fractal dimensions using light diffraction; particle sizing (using light diffraction, time-of-flight instrument); x-ray diffraction; scanning and transmission electron microscope imaging techniques; and focused ion-beam imaging to see internal structure of particles. She has been involved in various collaboration projects with:

  • Intensive Care Units, Royal Prince Alfred Hospital (Sydney) to develop an in-line device for administering dry powder mannitol to ventilated patients for the clearance of mucus from lungs.
  • Prince Charles Hospital (Brisbane) to characterise antibiotic droplets’ particle size distribution and mass output when the drug is nebulised in line with a ventilator.
  • Center for Neuro-Medicine, Korea Institute of Science and Technology, to synthesise liposome and characterisation of the droplet’s size when administered using a micro-sprayer. School of Health Science,
  • The University of Wollongong to prepare a stable form of beta-glucan extracted from shiitake mushroom for the prevention of colon cancer.

She has been successful in producing inhalable and stable drug compounds by ultrasonic precipitation, confined liquid impinging jet crystallisation, vortex mixer precipitation, high gravity reaction, spray drying and freeze drying.
