Fei XIE received his Phd in biology from the Fudan University and Westlake University in Jan, 2024. He worked as a research associate at Westlake University (Jan, 2024–Feb, 2026). In Mar, 2026, he moved to the University of Hong Kong and was promoted to be a postdoctoral. His research training spans developmental biology, cancer biology and tumor immunology. He has built solid and profound understanding of lung and mammary gland development and disease progression. His core research interest lies in tissue homeostasis, a determinant for tissue structural integrity, organ function and host defense against diseases. Unravelling how tissue homeostasis is sustained is instrumental to our comprehension of organ development and disease onset and progression.
