Nature contains a range of biomaterials that possess extraordinary features that are often the source of inspiration for developing next-generation materials.  One main focus of our group is on bioadhesives of spider silks, gecko setae, bacterial and so on, which show intriguing behavior governed by factors including complex molecular design, mechanical strength, humidity, and self-cleaning, to name a few. Their unique properties lay a strong foundation for research in developing new bioinspired materials. Inspired by bird feathers colors, we also explore structural colors, which are remarkable for their color tunability and resistance to chemical and photo bleaching compared with traditional pigmentary colors. Overall, our group studies the basic principles governing these unique systems and utilizes the concepts to develop engineered materials.
