刘宇博，教授，博士生导师，主要研究方向为糖生物学和糖化学生物学。

糖链是继核酸、蛋白质之后的“第三条生命之链”，与癌症等重大疾病发生发展息息相关。针对生物体O-GlcNAc糖链特异性标记和功能解析这一科学问题，构建了整套活细胞染色质糖蛋白标记的化学基因组学策略。实现了糖蛋白生物正交标记与高通量活性分析，组学水平揭示了染色质O-GlcNAc特征糖基化作为新的表观密码（糖密码）的重要功能，发现了多个肿瘤治疗新靶点。创制了特定O-GlcNAc糖基化的高效抑制剂分子，成功干预肿瘤异常O-GlcNAc糖基化，抑制多种类型肿瘤进展。研究工作在领域内形成鲜明特色，开辟了利用化学标记跨维度研究染色质糖密码功能的新途径，为糖生物学研究提供新范式和新策略。

发表高水平论文50余篇，包括中科院一区10篇，自然指数期刊3篇，主持国家自然科学基金等项目十余项，参与国家重大科技专项等。
