Dr. Yahnke received his B.S. in Engineering Physics from the Illinois Institute of Technology and his Ph.D. in Physics from Northwestern University. He joined Kenall in 2013 bringing over 25 years of photonics and healthcare experience in a range of fields related to defense, telecommunications, radiation oncology, medical imaging, analytical instruments, and surgical lighting to Kenall. As one of the inventors of Indigo-Clean, Dr. Yahnke has led its development and introduction into healthcare facilities across the US. Widely regarded as the industry expert on visible light disinfection, he has authored numerous articles on it and led numerous studies demonstrating Indigo-Clean’s ability to reduce bacteria and infections in clinical settings. His current research interests are focused on the transmission of bacteria in the perioperative setting, its impact on various surgical modalities, and the use of visible light disinfection in combating SARS-CoV-2 transmission. Most recently, Dr. Yahnke was part of the team whose ground breaking research into SARS-CoV-2 disinfection using visible light was published in Nature-Scientific Reports.
