John Rambo, Ph.D.
Computational biologist moving from single-cell & spatial multi-omics into connectome-scale neuroscience

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.

Experience

Postdoctoral Researcher
2025–2026
Nakdong University Wonju College of Medicine · Physiology / Cellular Systems Research Center
Developed deep-learning multimodal-integration models fusing imaging, transcriptomic, and clinical data into single predictive models.
Associate Director
2023–2025
Meridian Immune Therapeutics Inc. · Basic Research, Seoul
Built in-house single-cell & spatial transcriptomics analysis code from scratch; led cross-functional NHP (cynomolgus, marmoset) EAE/MS multi-omic studies; oversaw regulatory documentation for an anti-CD25 humanized-antibody program.
