We are interested in the use of biopolymers for printing both in 2 and 3 dimensions.  We study the generation of filaments, the formation of materials and interface of materials with printing setups (extrusion, piezoelectric, filamentary,  photochemically assisted, electrospinning).  The scope of this research is to build functional printed structures whether for smart textiles, tissue scaffolds, or for optical waveguiding.

Silk fibers produced in our lab are most notable for fitting the length scales that are relevant for single and multimode fibers (10-100 μm) and take shape without the use of any harsh solvents.  Multiple printing setups are available to customize outcomes for either technological or life science uses.
