General Information

Peter S. Popolo, Ph.D., is a Lecturer in the Biomedical Engineering department. He holds a Ph.D. in Speech and Hearing Science from The University of Iowa, and BS and MS degrees in Electrical Engineering from Rutgers University. He has worked in the medical device industry, where he developed speech and image processing products used by ear, nose, and throat (ENT) physicians. As a software developer and founder of Digital Health Applications, he created an iPhone app to study how daily videoconferencing during the Covid-19 pandemic impacts the voice. Dr. Popolo was a Research Engineer and Voice Scientist at the National Center for Voice and Speech, where he designed and built the Voice Dosimeter, an ambulatory voice monitoring device to study vocal fatigue in teachers, and he performed research in the areas of speaker identification and quantitative laryngeal imaging. His university teaching experience includes The University of Iowa, where he taught Instrumentation for Voice Analysis, and Acoustics of Speech and Hearing. His current interest is using vocal biomarkers (i.e., acoustic features of the voice) in conjunction with machine learning to screen for illness, such as Covid-19 infection, and to diagnose or monitor diseases, such as Parkinson’s or heart disease
