Dr. Lim's research concentrates on Digital Tools (methods, techniques and strategies) - an umbrealla that covers X-Reality and haptics, Cyberphysical systems, Gamification and Serious Games, Knowlegde capture, Data managment and visualisation. He is involved in virtual environment and systems to conduct DFMA (design for assembly and manufacturing) analysis and DFAM (design for additive manufacturing). He has been involved with the fabrication of structures for securing optical components through layer based rapid prototyping technologies. Dr. Lim actively researches novel algorithms used in computational geometry, specifically in the area of solid and mesh modelling. His interest is in applying computer graphics, computational geometry and engineering principles to medical applications relating to maxillofacial and cranial reconstruction. Another area of research is in bio-inspired design, manufacturing and cybernetics on the development of 'living' autonomous machinery (e.g. mirco and macro scale robots). Research interests include, but not limited, to the following topics: Rapid Field Deployable Prototyping (RFDP)Technologies, Operational research, Discreet event modelling and simulation in PLM/CAE, Automatic Feature Recognition (AFR), Wet-ware IIOT and wearable robotics.
