We work on redefining technological components such as optics, electronics, micromechanics, and nanostructures to resorb into the surrounding environment or in living tissue without harmful effects and at programmable timescales. 

This work is inspired by applying tissue engineering paradigms (scaffolds that remodel) to high tech (photonics that are living and remodel) and is based on the early collaboration with the Biopolymer Engineering group here at Tufts in 2006.  The work has since grown to cover multiple contexts and applications embracing ever evolving technological sophistication.

This approach challenges traditional form and function and design metrics that are typical of the technological world where materials are  designed to remain invariant over time.  

This research has important applications in medicine, distributed monitoring, and new bio-functional devices.  Further, the development of functioning technologies based on water-based processes from naturally derived materials has important implications for sustainability, energy efficiency and environmental impact of materials.
