The story of Qi Chen’s research is full of serendipity. In the first year of her Ph.D., she was hanging out with friends at the University’s Zernike campus, discussing the topics of their research. Chen told them she was going to study foam-like materials. A friend was casually peeling the stem of a grass-like plant, thereby revealing its insides that appeared to have an open and airy structure. He suggested jokingly that Chen might want to study it. She put it in her backpack and then forgot all about it.
