个人简介: 

长期从事宇宙学前沿研究。尤其是致力于第四代星系巡天实验的数据分析工作，发展了一系列创新分析方法，显著提升了提取宇宙学信息的能力：（1）提出“标准形状”探针新分析方案，指出干扰分析的星系本动效应虽然很强，但在宇宙不同演化时期表现出较强的相似性，可通过跨红移数据比对予以大幅消减。该方法避免了对红移畸变的复杂建模，将分析尺度推进至约5 Mpc，使暗能量、暗物质、哈勃常数及中微子等关键参数的约束能力提升40%–100%。（2）利用深度学习技术处理复杂数据中的非线性物理，发展了高效的宇宙学参数推断及宇宙速度场重构方法。特别地，实现了星系本动速度及其旋度场的高精度重建，相比基于微扰论的传统技术有实质性提高。（3）提出基于β-网络的非线性-线性自适应宇宙结构刻画方法，并发展了融合局部环境信息的关联统计工具，显著提升了宇宙学统计的分析能力，为构建宇宙仿真器提供了新途径。上述成果对提升大规模星系巡天的科学产出具有重要价值，受到包括诺贝尔奖获得者、邵逸夫奖得主在内的国际同行广泛关注与积极评价，并被美国天体物理学会及国内外多家媒体报道。

此外，在人工智能天文学、计算天体物理、高能天体物理、引力波天文学等领域亦有涉猎，并与相关领域专家保持多项合作。迄今已发表学术论文70余篇，其中第一作者或通讯作者论文50余篇，总引用2000余次。
