Nano/Micro-Scale Investigation of Multi-Physics Systems
Mechanics issues in many multi-physics systems limit the system performance. For example, lithium-ion
batteries (LIBs) are widely used energy storage systems for consumer electronics, zero-emission electric vehicles, and stationary power management, due to their superior performance. In LIBs, electrochemical, thermodynamic and mechanical processes work together to determine the
battery performance. The development of next-generation, high-performance lithium-ion batteries has been substantially hindered by mechanical degradation and the resulting capacity fade in high-capacity electrode materials. Our goal is to develop high-performance electrode and electrolyte materials for next-generation batteries by studying the mechanics aspect of battery materials with an integrated experimental and computational approach.

Design and manufacturing of stretchable 3D architectures and electronics
Complex three-dimensional (3D) functional architectures are of widespread interest due to their potential applications in biomedical devices, metamaterials, energy storage and conversion platforms and electronics systems. Our goal is to explore mechanics-guided assembly approach and its combination with existing technologies such as 3D printing for 3D architectures and electronics. Materials of interest include smart materials (shape-programmable materials), metals and a heterogeneous combination of those materials. We will also explore the various applications of 3D architectures and electronics.

Soft materials and systems
Soft materials, which can be easily deformed when exposed to external stimuli, have attracted considerable attention in various applications such as stretchable and biointegrated electronics, advanced energy harvesting and storage, soft robotics and machines, sensory skins, and drug delivery. Our goal is to design and fabricate soft materials and systems that can be used for various applications.
