Research Themes

Research

The lab studies how materials, interfaces, and processing windows can be engineered so energy devices continue to work under demanding environments and use conditions.

Each research area below highlights the technical problem, the lab's approach, and the kinds of contributions students can make.

Materials & Process

Build the material system

Students work on synthesis, formulation, interfacial control, and process tuning rather than only running downstream tests.

Characterization

Prove what changed

Electrical, thermal, and reliability measurements are treated as evidence for mechanism and process quality, not just a checklist.

Translation

Connect to devices and output

The research is framed so material advances can support functioning devices, credible claims, and eventually strong publications.

Deep sea mission equipment and harsh marine conditions
Operating conditions in deep-sea systems can amplify small interfacial failures.
Satellite and space environment
Space environments add thermal cycling, low pressure, and long-duration reliability demands.

Theme 01

Energy Transmission in Extreme Environments

Problem. Electric energy transmission in deep-sea, space, and deformable systems requires interconnects that survive pressure, temperature variation, low-pressure conditions, and repeated mechanical stress.

Approach. The lab studies materials selection, interface engineering, and fabrication routes that preserve conductivity while reducing thermal and mechanical mismatch across the structure.

  • Define failure modes in harsh mechanical and thermal environments.
  • Develop robust interconnect fabrication strategies for long-duration use.
  • Benchmark reliability with conditions that map to realistic deployment.
Deep Sea Space Soft Interconnects Reliability
Selective ion boosting system and ion transport concept
Selective ion boosting concepts point to device functions beyond standard electronic transport.
Soft via processing and polymer-compatible routing
Processing conditions matter as much as composition when polymer systems are involved.

Theme 02

Ion-Based Energy Control in Polymer Systems

Problem. Ionic transport is slower than electronic transport, but ion concentration gradients and ion-polymer interactions can create useful memory, thermal, and adaptive behaviors that standard systems do not offer.

Approach. The lab investigates ion-gel composition, polymer-network structure, and 3D processing conditions so ionic dynamics can be tuned into stable and controllable device functions.

  • Engineer ion transport pathways inside polymer matrices.
  • Connect processing conditions to switching and thermal response.
  • Translate ionic effects into practical sensing and control functions.

Theme 03

Wide-Bandgap Routes for High-Power Electronics

Problem. Demand from electric vehicles, AI infrastructure, and power systems is pushing beyond conventional silicon, but scalable routes for materials such as GaN and SiC remain a core challenge.

Approach. The lab explores liquid-metal-assisted processing in ambient environments to lower fabrication barriers while maintaining the interfaces and structures needed for high-performance device modules.

  • Address material constraints for high-voltage and high-temperature operation.
  • Use liquid-metal-enabled fabrication under more accessible conditions.
  • Target processing paths that can scale beyond isolated demonstrations.
