李嘉禹教授获得过百人计划、杰出青年基金等的资助，在几何分析领域取得了重要研究成果。在非线性方程解的紧性与奇点研究这一重要且困难的课题中，研究了一般情况下稳定调和映照的紧性，得到了有关弱极限和能量集中集的奇点公式，提出了弱极限稳定的充要条件并举例加以说明，把该困难问题的研究向前推进了一步。构造一个新的发展方程来研究极小曲面的存在性问题。证明了非紧情况下Narasimhan-Seshadri、Donaldson、Uhlenbeck-丘成桐定理，得到了稳定抛物丛上的陈数不等式，成为研究模空间的基础。在Kazdan-Warner 问题、高余维平均曲率流等方面的研究也取得了重要突破。
曾在联合国教科文组织-国际理论物理中心ICTP任研究员(2004年至2009年)，负责几何与分析国际合作方面的工作，为发展中国等第三世界国家的数学科学做出贡献。曾获中国数学会陈省身数学奖、香港求是科技基金会杰出青年学者奖等。
