Core Viewpoint - The article highlights the return of Chinese scholar Zheng Yu from the United States to join Peking University, emphasizing her significant academic achievements and the growing trend of top scientists returning to China due to improved academic opportunities and concerns about the Western research environment [1][4]. Group 1: Academic Background and Achievements - Zheng Yu, a young scholar focused on wearable devices, has transitioned from MIT to Peking University as a researcher and doctoral advisor [1]. - She graduated from Nankai University in 2017 and pursued her PhD at Stanford University under a renowned scholar in flexible electronics [1]. - After completing her PhD in 2022, she conducted postdoctoral research at MIT and received the "Young Chemist Award" from IUPAC and Solvay Group for her doctoral thesis [1]. Group 2: Research Focus and Applications - Zheng Yu's research areas include organic functional materials, polymer physics, and bioelectronic devices, with a focus on developing precise medical devices and efficient smart computing systems [3]. - Her research group aims to construct multifunctional integrated dynamic polymer networks at the molecular level, exploring the relationship between polymer network structures and the macroscopic performance of materials and devices [4]. - The research is divided into three main areas: transport mechanisms of organic mixed ionic-electronic conductors, molecular mechanisms of conductive polymer network mechanics, and the design of new flexible and stretchable packaging materials [4]. Group 3: Trends in Scientific Community - There is a noticeable trend of overseas scientists returning to China, driven by various factors including a lack of belonging in the West and concerns about the political environment in the U.S. [4]. - The increasing academic strength and talent pool in China are cited as major attractions for these researchers [4].
