Dr. Joshua Glasner currently serves as Assistant Professor of Speech-Language Pathology at Delaware Valley University in Southeastern Pennsylvania. There, he teaches Research Methods, Speech and Hearing Science, Instrumentation, and Introduction to Audiology. He previously taught voice performance, voice pedagogy, and music-related courses at Clarke University, New York University, and Coastal Carolina University. He also has taught courses in voice pedagogy and voice research & technology at the University of Delaware, Westminster Choir College’s Summer Voice Pedagogy Institute, and the Borough of Manhattan Community College. He serves as summer faculty for the Westminster Choir College Summer Voice Pedagogy Institute and has served as guest faculty for the Acoustic Voice Pedagogy Workshop at New England Conservatory. He has worked as a voice research consultant for startup ventures and is an active voice researcher. In 2021, Dr. Glasner was selected to participate in the presitigious NATS Intern Program at Georgia Southern University where he interned with NATS Master Teacher Theresa Brancaccio.
Dr. Glasner’s multidisciplinary research involves topics including historical recording technology, treatment efficacy, room acoustics, and singing voice science. In 2016, he
was selected to present his dissertation topic at the Voice Foundation’s New Investigator Research Forum where he received mentoring by leaders in the voice science community. Since then, Dr. Glasner’s work has been presented at various national and international conferences including the Voice Foundation Symposium, the International Congress of Voice Teachers, and Meetings of the Acoustical Society of America. His dissertation was completed in collaboration with the Thomas Edison National Historical Park (West Orange, NJ) and with the help of professional opera singers in New York City. It used modern signal processing methods to help the field of vocal pedagogy understand historical singing techniques given the limitations of historical recording technology. A portion of this study related to vibrato measurements is currently in-press with the Journal of Voice. More recently, Dr. Glasner’s research has branched into studying listener perception of singing, historical vocal pedagogy, the transgender singing voice, and teaching efficacy.
As a performer, Dr. Glasner most recently sang the role of Don Pedro in Asheville Lyric Opera’s production of Béatrice et Bénédict (Berlioz). He has also portrayed Guglielmo in Cosi fan tutte, the title role in Don Giovanni, and Dr. Cajus in Die lustigen Weiber von Windsor (Nicolai). He performed as part of the Westminster Symphonic Choir with the Berlin Philharmonic, the Philadelphia Orchestra, and the New Jersey Symphonic Orchestra, and has sung as a soloist with the Reading Symphony Orchestra. In addition to Western operatic repertoire, Dr. Glasner is passionate about song repertoire; having performed Schubert’s Winterreise in its entirety in 2018 in recital in New York.
In the community, he has served as Director of Music Ministries 
at Reformation Evangelical Lutheran Church (Exeter, PA) and Bethesda United Methodist Church (Middletown, DE) where he integrated functional voice instruction with community and choral singing. Dr. Glasner is passionate about breaking down barriers that traditionally separate academia and the general public; frequently working with secondary school music programs, church choirs, and various groups around the United States to teach singers of all ages and backgrounds how to use evidence-based tasks to improve their singing and speaking. He is constantly looking for ways to give back to the community and has volunteered with local young adult music groups and individuals in New York City as a voice teacher, vocal coach, and voice consultant during group and individual recording sessions.
Dr. Glasner holds a Ph.D. in Voice Performance (Vocal Pedagogy Specialization) from New York University’s Steinhardt School of Culture, Education, and Human Development. During his time at NYU, he studied vocal pedagogy and voice science through an interdisciplinary curriculum that combined Vocal Pedagogy, Voice Performance, Music Technology, and Speech Language Pathology. Additionally, he holds degrees from Westminster Choir College and University of Delaware in Vocal Pedagogy and Performance (Pedagogy Emphasis) and Applied Voice, respectively, and a Certificate in Vocology from the National Center for Voice and Speech (NCVS). He is affiliated with the Voice Foundation, the National Association of Teachers of Singing (NATS), the Pan-American Vocology Association (PAVA), and the Acoustical Society of America.
