Dr. Jifei Ou, who received his PhD and graduated from the Tangible Media group in 2019, started a company called OPT Industries, Inc., based on his PhD thesis project, Cilllia. He prototyped nasopharyngeal swabs based on Cilllia, a method of 3D printing hair-like fibers that Jifei developed in the Tangible Media group. He is now fabricating swabs for the testing of Covid-19 infections. This is a collaboration between Dr. Jifei Ou's OPT and Formlabs, another ML startup.
