Fall 2025

October 28th: The Root Lab has been awarded our first grant! We are grateful to the Petroleum Research Fund of the American Chemical Society for a Doctoral New Investigator Award to support our fundamental research into “Thermal Transport and Dielectric Stability in Macromolecular Composites of Liquid Metal Microdroplets.”

August 22nd: Sam Root won the 2025 Young Alumni Award from the Department of Chemical Engineering at the University of Rochester!

August 15th:  Our work was featured on the cover of Device by Cell Press!

On the cover: Healthy human skin can sense damage and trigger a repair process, facilitating
the functional recovery of multilayer structures through a concerted process at the
molecular, cellular, and tissue levels. <a href="https://www.cell.com/device/fulltext/S2666-9986(25)00115-2" target="_blank">Root et al.</a> present a multilayer electronic skin that can detect and heal from needle punctures
and scalpel incisions. These bio-inspired capabilities have broad implications in
the design of surgical simulation technology and damage-intelligent soft robots.

May 19th: Our paper describing the invention of a self-healing, damage-perceptive electronic skin was published in Device by Cell Press. By leveraging autonomous alignment in immiscible self-healing composites and a multilayer circuit design, we demonstrate three-dimensional damage sensing with millimeter resolution.

May 4th: Sam Root was awarded the Glennan Fellowship from CWRU ($7k) to support the development of a new elective course, “Polymer Composites for Electronics” aimed at preparing polymer engineers for high tech manufacturing industries through experiential education including laboratory design and testing of composite materials and devices. 

May 2nd: Congratulations to Trevor Swan, who has been selected as a SOURCE STEM 2025 Summer Research Scholar through the Undergraduate Research Office at CWRU!

I spent 6 months on ‘sabbatical,’ working as a scientific consultant for Thintronics Inc., a Bay Area startup company developing high performance insulator technology for applications in AI data centers, networking, RF, and other electronic devices. I had an amazing experience working with the Thintronics Team and I am looking forward to future collaboration.
