Translating Nature Inspirations into Technology of Tomorrow

Various life forms in nature display a high level of adaptability to their environments through the use of sophisticated micro/nanostructured material interfaces. This is exemplified by numerous examples, such as the ultra-slipperiness of pitcher plants, the self-cleaning of lotus leaves, the tunable-adhesion of gecko feet, the water-walking ability of water strider, and the water desalination of mangrove. Incorporating these natural functions into artificial materials would dramatically enhance their functional capabilities.

 

To this end, our group is interested in translating the concepts from nature into technology innovation, with the goal to improve the quality of human life. Specifically, we focus on utilizing biologically inspired concepts to design functional and adaptive interfacial materials that not only will augment the capabilities of humans to interact with their environments, but will also allow for a broad range of applications related to energy, water, and health - three important elements for sustainability.

 

Simply put, we are a group of scientists and engineers who provide nature-inspired solutions to critical engineering challenges facing the society in the 21st century.
