Please welcome Dr. Bin Gu to the Obstetrics, Gynecology and Reproductive Biology and Institute for Quantitative Health Science and Engineering. Dr. Bin Gu received his Ph.D. in Cell Biology from the College of Life Sciences at Zhejiang University in China in 2013. There he discovered the expression and function of the Autoimmune Regulator (Aire) gene in embryonic stem (ES) cells. In 2013, he moved to Toronto for his postdoctoral training in Dr. Janet Rossant’s Lab in SickKids Hospital. During his postdoctoral training, he continued to study the function of Aire in early mouse embryos and revealed a novel function of Aire in mitotic spindle assembly in ES cells and early embryos, and provided a plausible explanation for the fertility defect in AIRE mutant APECED patients and Aire knockout mice. Recently, Dr. Gu has developed 2C-HR-CRISPR, a transformative technology for complex genome editing in mice.
