Postdoctoral applicant · computational single-cell
Geralt Rivia, Ph.D.
Computational biologist moving from single-cell & spatial multi-omics into connectome-scale neuroscience.
01 Profile
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. Research objective: connect molecular cell identity to circuit structure and function by integrating connectomics with transcriptomics, growing into connectome-constrained circuit models.
