Abstract: Functional polymers provide a versatile platform for engineering materials in which ionic, 
electronic, and mass transport can be tuned through controlled nanostructure. Yet achieving 
predictive performance in these systems requires understanding how phase behavior, nonequilibrium assembly, and solid-liquid interactions govern structure formation across multiple 
length scales.

Morphology and phase segregation fundamentally dictate charge and ion transport in applications 
ranging from ion-selective membranes to bioelectronic devices and biosensors. In this talk, I will 
discuss how nanoscale domains, interfacial structures, and nanoconfinement govern ionic 
partitioning and electronic percolation, and how these structural parameters can be deliberately 
engineered to control transport behavior and electrochemical response. By integrating materials 
design with quantitative nanoscale analysis enabled by cryogenic electron microscopy, we 
establish structure-transport relationships that support the predictive tuning of polymer blends for 
targeted applications.
