My Research Group

Our research program on Medical Devices, Robotics, Imaging, and Simulations are supported by research grants from various sources. I am grateful to the support from funding agencies, as well as my collaborators and colleagues.

Our work typically involves designing and building mechanisms, implementing control systems and then optimizing the intelligent systems for specific application. There are aspects of mechanics, electronics, computing and medicine involved in our work. Between 2011 and 2016, we had an almost equal distribution of publications in Engineering, Computer Science and Medicine (Source: SciVal – 26 July 2016). The advances in cyber-physical systems and AI technologies in recent years have created many possibilities. Since 2015, we have been developing these technologies to build smarter and more intelligent systems and solutions. Below is a treemap showing the distribution of our publications by subject between 2018 and 2023 (Source: SciVal – 21 June 2023).

Segment size represents relative publication share per Subject Area. Note that a publication can be mapped to multiple Subject Areas – Engineering (58.6%), Computer Science (79.3%) and Medicine (20.7%).

Our non-medical projects include robot-assisted cable binding for shipbuilding with Sembcorp Marine, intelligent thermal control of data centers in collaboration with A/Prof PS Lee of the Thermal Division, and automation of drug discovery and development in collaboration with colleagues from Chemical Engineering and Chemistry departments.

We can broadly represent our scientific contribution using the following keywords: Cyber-physical Systems; Imaging, vision, and graphics; Interaction, Virtual/Augmented Reality, and Simulations; Learning-based Control; Mechanics of tissue and biomedical materials; Medical Devices; Robotics; and Variational Methods. In many cases, there are overlaps in two or more areas. For example, we developed a new constitutive model for the liver organ, enabling realistic tissue deformation in medical simulation and accurate needle insertion in robot-assisted surgery.
