Research

Porous materials underpin many electrochemical energy technologies, yet transport within them is inherently heterogeneous and difficult to predict. My work investigates how pore structure, wettability, and operating conditions govern multiphase transport across length scales, with a particular focus on fuel cells, electrolyzers, and batteries. By combining experiments and quantitative analysis, I aim to uncover transport mechanisms that directly impact device performance.

I develop and apply operando X-ray and neutron tomography techniques to directly visualize structure, transport, and degradation inside working energy devices. This includes multimodal and time-resolved imaging under realistic operating conditions, enabled by close collaboration with synchrotron and neutron facilities. These tools provide otherwise inaccessible insight into how devices function internally.

Electrochemical device performance and lifetime are tightly linked to evolving microstructure. My research connects microstructural changes, such as deformation and phase redistribution, to measurable performance losses and failure modes. This structure-to-function perspective enables targeted diagnosis of degradation mechanisms across batteries, fuel cells, and electrolyzers.

Insights from operando characterization and transport physics can be translated into improved material architectures. I use experimental data and physical understanding to guide the design of porous layers, electrode architectures, and composite materials for enhanced performance and durability. This work bridges fundamental understanding with practical device-level innovation.
