Research Overview

The Yu Group conducts research at the intersection of Solid Mechanics, Materials Science, Biology, and Advanced Manufacturing. We advance the fundamental understanding and design of next-generation materials, bridging molecular- to structural-scale phenomena to enable transformative engineering and infrastructure applications. Our work spans natural and synthetic materials - including natural fibers, minerals, cementitious systems, and hydrogels—as well as hybrid living material systems, where living cells are integrated with engineered substrates to achieve unique functionalities such as controlled mineral formation, self-repair, and dynamic environmental responsiveness. 

Our research integrates mechanics and materials theory, innovative material synthesis, architected structural design, and advanced manufacturing methods. This combined approach allows us to uncover new scientific principles while creating practical pathways for real-world technologies. 

Current Research Areas

• Mechanics of Engineered Controlled Living Materials: We investigate how mechanical loads and environmental stimuli influence the behavior of living cells within engineered systems, with the goal of enhancing material performance through controlled biological–mechanical interactions.

• Design of Novel Materials: We develop materials that incorporate natural compounds, synthetic chemistries, and/or living components to address challenges in infrastructure, energy, and environmental engineering. 

• Advanced Manufacturing: We explore the integration of cutting-edge manufacturing techniques, including 3D printing and robotic fabrication, to create architected materials and structures with tailored, tunable, and multifunctional properties. 

Vision and Impact

Our overarching aim is to deepen fundamental understanding at the molecular and microstructural scales and translate this knowledge into impactful solutions for engineering and environmental challenges — including building energy efficiency, novel material functionality, mitigation of greenhouse gases, water resource management, and the enhancement or restoration of structural performance.

Beyond these core areas, we actively seek collaborations across disciplines and are continually expanding into related research fields. For our most recent work, please visit the Publications page.
