01

Problem or Industrial Need

No single model explains how nanoscale morphology, transport, mechanics and electromagnetic response combine in a sensing material.

02

Engineering or Scientific Solution

A computational stack that moves between RVE, resistor-network, diffusion, mechanical and electromagnetic models and closes the loop with experiments.

03

Sebastian's Technical Contribution

Developed, coupled and evaluated numerical workflows across physical scales, then used experimental evidence to test their explanatory power.
