Opportunity: Reprogramming the Gut-Brain Axis: Bioengineered Postbiotics for Radiation Resilience

When ionizing radiation strikes, hazardous environments don’t just damage physical tissue—they wage silent war on cognitive endurance.
Radiation-induced gut dysbiosis unleashes a cascade of inflammatory signals directly along the gut-brain axis, impairing decision-making, reaction speed, and cognitive clarity at critical moments. Conventional radiation countermeasures rarely address these lingering neurological and systemic challenges.
This project dares you to engineer biological countermeasures that defend both physiological resilience and cognitive performance. You will explore how engineered melanized probiotics (such as tailored E. coli Nissle) work in synergy with bioactive postbiotics—the potent metabolites, peptides, and protective biomolecules they produce—to actively remodel host gene expression, quench oxidative stress, and reinforce internal biological barriers.”
