About

  • Hi, I am Liyang. I received my Ph.D. in statistical genetics from Westlake University (joint program with Zhejiang University) in 2026, advised by Prof. Jian Yang. I am now a postdoctoral researcher in the Yang Lab at Westlake University.
  • My research sits at the intersection of statistical genetics and artificial intelligence. I develop statistical models and deep-learning methods that integrate single-cell and spatial omics data with human genetics, to identify the cell states and tissue locations associated with complex traits and diseases. Topics include:
    • Integrating GWAS with spatial and single-cell transcriptomics
    • Graph neural networks and deep learning for omics data
    • Mixed models and cellular deconvolution
    • Scalable, open-source software for large-scale genomic data
  • I developed gsMap (Nature, 2025), which maps trait-associated cells in tissue by combining GWAS summary statistics with spatial transcriptomics, and MeDuSA (Nature Computational Science, 2023), a mixed-model method for estimating cell-state abundance from bulk RNA-seq.
  • I am always open to discussions and collaborations — feel free to reach out via email. :)
