Research Summary

Moving from wet-lab immunology into computational neuroscience. I build methods that infer cellular identity, state, and interaction from large, incomplete single-cell and spatial data. My research objective is to connect molecular cell identity to circuit structure and function by integrating connectomics with transcriptomics, growing into connectome-constrained circuit models.

Interests: single-cell & spatial multi-omics; cell-type inference from incomplete data; self-supervised / embedding representation learning; connectome × transcriptomics; computational neuroimmunology; reproducible ML/DL analysis.
