David Welch, Ph.D

Associate Research Scientist at the Center for Radiological Research, Columbia University Irving Medical Center
Dr. Welch is an Associate Research Scientist at the Center for Radiological Research at Columbia University Irving Medical Center. Since joining Columbia University in 2013, Dr. Welch has participated in efforts to examine both the efficacy and safety of far-UVC radiation. The Columbia research team has demonstrated far-UVC inactivation of numerous viruses and bacteria on surfaces and while airborne. Safety studies to examine possible health hazards from both acute and chronic far-UVC exposures have also been explored. Dr. Welch has supported the experimental design and physics measurements throughout these studies. He is currently aiming to expand on our understanding of the specific health hazards from UVC wavelengths.
