Shu Yang

Shu Yang is a Chinese-American materials scientist who is the Joseph Bordogna Professor of Engineering and Applied Science and Chair of the Department of Materials Science and Engineering at the University of Pennsylvania. She is a Fellow of the Royal Society of Chemistry, American Physical Society, National Academy of Inventors and Materials Research Society.

Early life and education Yang was born in China. She attended Fudan University in Shanghai. She moved to the United States for graduate studies, where she joined Cornell University as a student in chemistry and chemical biology. She remained at Cornell for her doctoral research, where she worked on the design and synthesis of novel polymers for microelectronics. After graduating, she joined Bell Labs as a member of the Lucent Technologies.

Research and career In 2004, Yang joined the faculty at the University of Pennsylvania. She was promoted to Professor in 2013 and elected Chair in 2021. Yang is interested in the synthesis and fabrication of novel materials, including self-assembled nanostructures and responsive materials. Through the study of lotus leaves and butterflies, Yang created novel superhydrophic surfaces. These surfaces have very high nanoscale roughness, which reduces the contact area between water and results in water being repelled from the surface. To fabricate these surfaces, Yang pioneered the use of holographic lithography, using a laser to cross-link a photoresist. By introduce molecular ordering in two-dimensional sheets of a rubber-like material called liquid crystal elastomer, the Yang lab transforms the sheets into complex three-dimensional geometries, such as a human face, with heat. She is investigating self-morphing building blocks for novel manufacturing processes. These building blocks are based on biological systems and natural materials. For example, by studying snail slime she created a novel, reversible adhesive. By introducing holes and cuts in 2D sheets, Yang demonstrates dramatic color and shape change and super-conformability via collapsing or expanding of the hole arrays in the micro- and macroscales. By programming the geometry of cuts and fold using origami and kirigami mechanisms, Yang explores potential applications in water harvesting, super-stretchable and shape conformable medical devices.

During the COVID-19 pandemic, Yang was part of a team who created an origami-inspired face mask that could be used to address the shortage of personal protective equipment in hospitals. She shared the design through Open Medical and recommended the respirators be made using sterilisation wrap. The mask achieved a 95% viral filtration efficiency. 2011 American Chemical Society Arthur K. Doolittle Award 2015 George H.
