Rui is currently a postdoctoral researcher at the School of Biomedical Sciences at The University of Hong Kong, where she studies the role of retrotransposons in regulating early mouse embryonic development. She earned her PhD from the Max Planck Institute for Molecular Biomedicine in Germany, focusing on mouse pre- to post-implantation embryogenesis, embryonic diapause (delayed implantation), and stem cell biology, including embryonic and trophoblast stem cells. Rui has pioneered the use of single-cell transcriptomic technologies to investigate mouse embryo dormancy, significantly advancing the understanding of the cellular mechanisms that preserve developmental potential in dormant embryos. Her research was highlighted as a cover paper in the Cell Stem Cell journal in 2024.
