Ruifeng graduated from Xiamen University in 2020 with a B.S. degree in Biological Sciences. In the sophomore summer, he had his first research experience in autophagy. He then joined an immunology lab studying B cell central tolerance at Xiamen University. His interest in hematological malignancy was piqued when he did his graduation project at Yale in Dr. Joao Pereira's lab, where he studied how B-ALL impacted B lymphopoiesis. Outside the lab, Ruifeng enjoys swimming, cooking and watching anime.
