The Lewis Lab focuses on the programmable assembly of soft materials. Designing and fabricating functional, structural and biological materials with controlled composition and architecture across multiple length scales are specifically studied. Architected soft matter may find potential application as electronics, optical materials, lightweight structures, and 3D vascularized tissues. The group is divided into three main sub-groups with a rich and overlapping set of interests:

1) Functional Materials - The group is designing novel inks and printheads for printing functional materials with locally tailored composition, structure, and properties. Specific materials and devices of interest, include soft electronics, sensors, and robotics as well as customized rechargeable batteries.

2) Structural Materials - The group is designing lightweight architectures with locally tailored composition, structure, and properties. Specific materials and architectures of interest range from stimuli-responsive, shape-morphing hydrogels to epoxy-based composites.

3) Bioprinting - The group created a multi-material, bioprinting platform that enables the fabrication of 3D tissues composed of multiple cell types, engineered extracellular matrices, and vasculature. These vascularized tissues are under development for fundamental studies related to drug screening, disease modeling, and tissue repair and regeneration.
