Research Interests

Integrating the structure dependent function of self-assembling proteins and biopolymers into flexible devices for applications ranging from catalysis to wearable electronics

Current Research Interests

Our laboratory is an interdisciplinary group that works at the interface of bio-analytical chemistry, materials science, and design. Our primary research focus is building the structure dependent function of self-assembling proteins into macromolecular materials. Two of our ongoing projects to support this goal are described here.

Printing protein-based materials

We incorporate piezoelectric inkjet printing using a Dimatix Materials Printer (DMP 2800) to build custom protein based materials. As part of the materials design, our group formulates custom protein inks and examines the fluid physical parameters using rheology and an optical tensiometer prior to printing. Based on the bulk structure and composition of the protein based materials, they are then integrated with non-biological components (metals or metal oxides) to be used for applications including catalysis, diagnostic assays, flexible displays, or implantable sensors.

Building optical displays inspired by cephalopods

Cephalopods such as squid, octopus, and cuttlefish are capable of rapid (~100 msec) and adaptive changes in coloration by varying the local distribution of dermal pigments and proteins to reflect, absorb, and transmit light. We study the role of the cephalopod chromatophore organ in potentiating changes in coloration and apply our understanding to inform the design of new photonic materials.  More information on our squid dissections at UNH can be found here: https://www.youtube.com/watch?v=HOebH4pjakU.
