Dr. Woon Kai Lin obtained his PhD in University of Hull in photonic liquid crystal. After graduation, he worked as a postdoc in electroluminescent liquid crystalline light emitting display capable of producing 3D image funded by a start-up company and venture capitalists. He also spent a year as a Postdoc in Oxford University to study whether photonic crystals in nature can be adopted for industrial application. Later, he returned to Malaysia to work as OLED (organic light emitting diode) materials and device specialist under OSRAM. The project initially focussed in passive matrix OLED display and then later in OLED lighting using solution processable techniques. The works involved co-operation with well-known multinational companies such as Mercks, Sumitomo and Philips.  Later he joined University Malaya working in the field of organic electronics specializing in organic light emitting diode. The works including leading cost effective  synthesis of organic semiconducting materials for lighting application, interfacial physics and fundamental mechanism of high performance OLED, accurate computation of OLED materials, organic field effect transistors and phototransistors.  Some of the works carried out in the University of Malaya involves co-operating with various universities in the world, domestic and overseas start-ups and local SMEs. He is actively filing patents in the field of organic electronics.The ultimate aim is to enhance the performance to price ratio for organic electronics by investigating and optimizing critical parameters and mechanism in organic devices using various analytical and processing tools available domestically and internationally including the use of synchrotron facilities.He is also the  material science program co-ordinator setting new undergraduate Material science lab and program. Material Science under Physics department has been ranked the best in Malaysia and Faculty of Science.
