Journal Article Research in Mathematical Sciences · September 1, 2025 Full text CiteCluster-independent multiscale marker identification in single-cell RNA-seq data using localized marker detector (LMD).
Journal Article Communications biology · July 2025 Identifying accurate cell markers in single-cell RNA-seq data is crucial for understanding cellular diversity and function. Localized Marker Detector (LMD) is a novel tool to identify "localized genes"-genes exclusively expressed in groups of highly simila ...

Journal Article Nature biotechnology · February 2025 Single-cell RNA sequencing has been widely used to investigate cell state transitions and gene dynamics of biological processes. Current strategies to infer the sequential dynamics of genes in a process typically rely on constructing cell pseudotime throug ... Full text CiteRecent Grants
