B.S. degree in Chemistry from Tamkang University in Taiwan (1995)

My research focuses on three-dimensional (3-D) photonic crystal OLEDs (organic light emitting diodes) and hydrophobic/hydrophilic switching in 3-D microfluidic/nanofluidic channels. I am interested in the self-assembly of materials in 3-D, polymer chemistry, and energy storage materials.

I received my B.S. degree in Chemistry from Tamkang University in Taiwan (1995), and my M.S. and Ph.D. in Chemistry from National Tsing Hua University in Taiwan (2001). Then I joined the Polymer Battery Project of Industrial Technology Research Institute in Taiwan (2001-2006).

3-D Photonic Crystal Organic Light Emitting Diodes
Research on organic light emitting diodes (OLEDs) has attracted much attention in recent years due to their potential applications in flat panel displays and flexible displays. However, the low light extraction efficiency is one of the important issues for OLEDs.[1] In my research, I developed an OLED with a 3-D photonic crystal structure to suppress emitted light in certain directions and improve the emissivity in other directions.

3-D Hydrophobic/Hydrophilic Switching in Microfluidic/Nanofluidic Channels
Microfluidic/Nanofluidic devices are useful for handling small quantities of materials for fast, high resolution, and low cost analysis.[2] These devices have potential applications in medical diagnostics, chemical analysis, sensors, drug discovery, and microreactors.[3] Various methods have been developed to fabricate the channels. However, most fabrications are planar. Therefore, the goal of my research is to develop an easy and fast method to establish 3-D microfluidic/nanofluidic channels, which can conduct ions or molecules. Furthermore, I aim to investigate the diffusive transport of ions or molecules in 3-D microfluidic/nanofluidic channels.
