Michael Kozicki (pictured) is using his years of experience in micro contamination management to provide a useful service for health care workers in the midst of the COVID-19 pandemic. Kozicki, a Fulton Schools electrical engineering professor, has built a laboratory in his home to perform studies of ozone reconditioning of surgical masks and related medical gear. The reconditioning helps health care professionals keep their work and personal materials safe, as well as enabling reuse of critical medical items that are in short supply. This work became part of a program spearheaded by students at ASU’s Luminosity Lab who are now making and deploying sterilization systems to Arizona health care facilities.
