Computational methods grounded in biological mechanism.
My research connects representation learning, single-cell measurement, and experimental systems to make complex cellular behavior interpretable and testable.

CONCORD: coherent cell-state representations
A self-supervised framework for integrating, denoising, and reducing single-cell data while preserving local geometry and global topology.

What it shows
Dataset-aware and hard-negative sampling let a minimalist contrastive model resolve complex trajectories across batches, technologies, and species.
A statistical method for recovering sample identity and doublets from multiplexed single-cell experiments with noisy or unbalanced tag counts.
The core contamination model separates true tag signal from cell-bound and ambient background. Cropped from Figure 1a, Genome Biology (2024). Source ↗ · CC BY 4.0 ↗
What it shows
Mechanistic contamination models, negative-binomial GLMs, and expectation–maximization retain more high-confidence singlets.
Developmental trajectory of pre-hematopoietic stem cell formation
Single-cell transcriptomics resolved the endothelial-to-hematopoietic transition and the molecular progression toward pre-HSC identity.

What it shows
A continuous endothelial-to-hematopoietic trajectory revealed a developmental bottleneck before hemogenic endothelium and two temporally distinct hematopoietic outputs.
A lineage-resolved molecular atlas of C. elegans embryogenesis
A single-cell atlas connected transcriptional states to the invariant embryonic lineage, revealing how lineage history and cell fate organize development.

What it shows
More than 86,000 single-cell transcriptomes were mapped onto the known lineage, reconstructing developmental trajectories for nearly every embryonic cell type.
