The team of Mechanical Engineering Assistant Professor Ramathasan Thevamaran and postdoctoral researcher Jizhe Cai received the award for their work on a new, lightweight material to protect against bullets and other high-speed impacts. The engineers’ ultra-durable lightweight material made of carbon nanotubes shows unprecedented strength and a superior ability to protect against high-impact ballistics including bullets and air and space debris.

The second winning team includes Sara McCoy, associate professor of medicine; Miriam Shelef, associate professor of medicine; Michael Newton, chair of biostatistics and medical informatics; and statistics graduate student Zihao Zheng for their work on an innovative new diagnostic test for Sjögren’s Syndrome.

An independent panel of judges selected the winners from a field of six finalists drawn from several hundred invention disclosures submitted to WARF over the prior 12 months. The winning teams each receive an award of $10,000, with the funds going to the named UW-Madison inventors.

“Our Innovation Awards recognize some of the most exciting early-stage discoveries on campus,” says Erik Iverson, CEO of WARF. “We’re pleased to celebrate the nominees and the transformative work taking place across the UW-Madison community.”

Department of Mechanical Engineering faculty Melih Eriten and Corinne Henak were among the 2022 WARF Innovation Award finalists. Eriten and Henak developed a method for testing the mechanical and failure properties of soft materials using a non-contact, portable vibrometer that measures acoustic emissions.
