Biography

Florence Leong is a Postdoctoral Research Associate, working on the RoboPatient Project. Florence obtained her PhD from the University of Melbourne, Australia in 2019 and her Master of Engineering (by research) from the National University of Singapore (NUS) in 2010, both in the area of Surgical Robotics.

Florence has worked in multiple medical companies in the past years. She joined Siemens Medical Instruments, Singapore in 2011 as an R&D Automation Engineer and then a Technical Project Leader. In 2019, she briefly worked in Axxin Pty Ltd, a company in Australia which produces biomedical diagnostic instrumentations, as a Systems Engineer before moving to the UK for her postdoctoral research position.

Description of Current Research

Florence’s research focus in the RoboPatient project includes the modelling and analysing the behaviour and perception in the interaction between tissue and touch during medical examination palpation on patients. These interaction scenarios are simulated using numerical/analytic and finite element modelling methods. The observations from the models will be used to construct a surrogate model (e.g. augmented reality) to be integrated with a robotic patient platform for medical training to minimise examination practices on actual patients, hence reducing trauma and discomfort in patients.

Research Background
