About Celina Peng
In 2023, Celina Peng led the structural redesign of a stabilized RSV F glycoprotein immunogen that achieved 92% neutralization breadth across 47 clinical isolates, a leap beyond prior candidates that failed in Phase II due to conformational instability. She doesn’t treat antigens as static targets but as dynamic molecular machines, mapping their energy landscapes using cryo-EM time-series and machine-guided mutagenesis. Her lab’s open-source ‘Epitope Resilience Score’ framework is now embedded in WHO’s preclinical vaccine assessment guidelines for emerging paramyxoviruses. Celina works with protein engineers, not just as collaborators but as co-translators, she insists on annotating every construct with its thermodynamic penalty and predicted glycan shielding drift over 18 months at 37°C. Her notebooks contain hand-drawn folding pathways alongside Python snippets, and she refuses to run a single assay without first modeling its failure modes in silico. This isn’t about speed or scale, it’s about making biologics that hold their shape, function, and fidelity long enough to train human immunity correctly.
