Zefeng was born in Xiamen, a lovely coastal city in southern China. He obtained his bachelor’s degree in Chemistry at Xiamen University, where he received research training in Prof. Hai-Chao Xu’s lab. After graduation, he went to Boston to pursue his Ph.D. under the supervision of Prof. Jia Niu at Boston College. His research was focused on regulating the polymer chain-end in ring-opening metathesis polymerization (ROMP). Specifically, he developed a catalyst encapsulated in a metal-organic framework for the ROMP of low-strain monomers, achieving an ultra-high-molecular-weight polymer and a class of single-addition monomers serving as highly efficient chain-end functionalization agents. Zefeng joined the Stache Lab at Princeton University in 2025. In his free time, he enjoys playing badminton, hiking, and enjoying delicious food.
