简 历：
中国科学院上海天文台研究员、博士生导师。2010年获得云南大学应用物理学学士学位，2016年获得中国科学院上海天文台天体物理学博士学位。2015—2022年，先后在加州大学洛杉矶分校、中国科学技术大学、伊利诺伊大学香槟分校和加州大学欧文分校联合培养或从事博士后研究。2022年通过中国科学院高层次人才引进至中国科学院上海天文台工作；2025年获得国家自然科学基金青年科学基金项目（B类）资助。
主要研究领域为活动星系核与黑洞天体物理，重点开展黑洞相关的多波段时域观测研究，包括中等质量黑洞的搜寻与认证、活动星系核光变与反响映射，以及暂现源的多波段观测。发起并领导中等质量黑洞反响映射国际合作项目（IMBH-RM Project），组织开展多波段、天地协同观测。作为项目负责人，带领团队先后获得JWST、HST、Chandra、XMM-Newton、Swift和爱因斯坦探针（EP）等空间观测设施，以及Subaru、VLT、Gemini、GTC、HSA、VLBA和EVN等大型地面观测设施的观测时间，累计超过800小时。截至2026年8月，已发表学术论文80余篇。
研究方向：
黑洞相关的多波段时域光变：反响映射，中等质量黑洞，超大质量双黑洞，潮汐撕裂事件，变脸活动星系核等
