Joyce Tiong

Associate Professor,



Joyce is currently working as an Associate Professor at the Department of Chemical and Environmental Engineering. She obtained her PhD from the University of Bath, United Kingdom in July 2012, focusing on sonochemistry (chemistry of ultrasound) on dental equipment. She is currently working on acoustic pressure prediction on various ultrasonically driven equipment and attempts to optimise their usage in various industrial fields, such as waste water treatment, drug delivery, dental practices and so on.

Teaching Summary

From the past to present, here are the list of modules that I have taught.

Research Summary

My past and present research area includes:

- Optimising the ultrasonic dental equipment experimentally and via simulation

- Optimisation of ultrasonically formed oil-in-water systems

- Synthesising and optimisation of sonocatalysts for hydrogenation of oil

- Simulation of acoustic pressure systems by incorporating attenuation coefficient and for multi-phase systems.

Past Research

Previously, I was working on ultrasonically driven dental equipment, focusing on endosonic files used for root canal treatments. In the study, I have developed various characterisation methods to evaluate the efficiencies of different endosonic files and correlating them to the cleaning effectiveness by doing various in-vitro studies on prototype models. This work ended with computational modelling on the acoustic pressure predictions to correlate and attempt to optimise the designs of endosonic files used for actual clinical treatments.
