2011年1月28日理论物理国际中心（the Abdus Salam International Centre for Theoretical Physics －ICTP）宣布将2010年度Ramanujan奖授予北京大学数学科学学院史宇光教授，以表彰他在完全（非紧）黎曼流形几何的研究中所做出的杰出贡献，也是对他十五年来在中国从事数学教学和研究中所做出的重要贡献的褒奖。

Ramanujan奖是专门为发展中国家的优秀青年数学家（四十五岁以下）所设立的，奖金为一万五仟美元。评选委员会由五位杰出数学家组成，他们是由理论物理国际中心和国家数学联盟（International Mathematical Union －IMU）共同任命的。

2009年史宇光教授曾经中国数学会推荐，荣获第十一届中国青年科技奖。

ICTP's 2010 Ramanujan Prize has been awarded to Professor Yuguang Shi of theSchoolofMathematical Sciences,PekingUniversity. The prize is in recognition of his outstanding contributions to the geometry of complete (noncompact) Riemannian manifolds, specifically the positivity of quasi-local mass and rigidity of asymptotically hyperbolic manifolds.
The prize is also in acknowledgement of the substantial contribution that Professor Shi has made to mathematics inChinathrough over 15 years of teaching and research.
The Ramanujan Prize, which is funded by the Norwegian Niels Henrik Abel Memorial Fund, is awarded annually to a researcher from a developing country less than 45 years of age on 31 December of the year of the award, who has conducted outstanding research in a developing country. Researchers working in any branch of the mathematical sciences are eligible. The Prize carries a $15,000 cash award. ICTP awards the prize through a selection committee of five eminent mathematicians appointed in conjunction with the International Mathematical Union (IMU).
