Dr. Jennifer Long is a surgeon-scientist in the Department of Head and Neck Surgery at the University of California, Los Angeles, where she also serves as the department’s Vice Chair of Research. Her research focuses on regenerative medicine approaches to laryngeal disorders, and has been funded by the National Institutes of Health and the Department of Veterans Affairs. Dr. Long’s clinical practice encompasses all aspects of laryngology and voice medicine, and she is a fellow of the American Laryngological Association. Before joining the faculty, she completed both residency in Head and Neck Surgery and fellowship in Laryngology at UCLA. Dr. Long earned her Medical Doctorate and a PhD in Chemical Engineering from the Medical Scientist Training Program at the University of Minnesota.

Jody Kreiman is Professor in Residence of Head and Neck Surgery and Linguistics at the University of California, Los Angeles, where her research focuses on voice quality. Most recently she has proposed a psychoacoustic model of quality and has applied that model to examine the acoustic dimensions that meaningfully distinguish one talker from another. She received her PhD in Linguistics from the University of Chicago in 1987, and is a Fellow of the Acoustical Society of America and of the American Speech-Language-Hearing Association.

David Berry has been a Professor of Head and Neck Surgery at UCLA for over 20 years. His research regarding basic mechanisms of regular and irregular vocal fold vibration has been funded by NIH/NIDCD for over 30 years. These mechanisms of vibration have been investigated using 3D high-speed imaging with various laboratory models of phonation, including silicone physical models of vocal fold vibration, the human excised larynx, and the in vivo canine larynx. Systematic studies of computer models of vocal fold vibration have also been employed to investigate these basic mechanisms. Among other things, his research has shown that many types of complex, irregular vocal fold vibrations, which appear high-dimensional in nature, can nevertheless be explained by just a few underlying modes of vibration, which are simply dis-entrained.

Dinesh Chhetri, MD, is Professor of Head and Neck Surgery and Vice-chair for clinical operations at the University of California, Los Angeles (UCLA). He graduated from the UCLA School of Medicine, where he completed his residency in Otolaryngology and fellowship in Laryngology. He is an actively practicing Laryngologist and a voice scientist funded by the National Institutes of Health (USA). His main research interests are neuromuscular control of the larynx, evaluating the connections between laryngeal neuromuscular stimulation, vocal fold vibration, and voice quality. For nearly two decades his research has focused on laryngeal physiology and biomechanics using the in vivo canine model of phonation. After developing the technique for graded stimulation of individual intrinsic laryngeal muscles, the individual contributions of the muscles on phonatory posture, aerodynamics, acoustics, and vibratory behavior were investigated. Current investigations are focused on 3D reconstruction of glottal vibratory deformation, effects of laryngeal muscle activation on glottal volume waveform, as well as the trajectories of the medial surface landmarks in relation to neuromuscular stimulation and vocal fold microanatomy. He is serving as Council Member of the American Laryngological Association (ALA) and elected President of the ALA for 2023-2024.

Zhaoyan Zhang is a Professor of Head and Neck Surgery at the University of California, Los Angeles. His current research focuses on how changes in vocal fold physiology affect voice production and how to infer vocal fold physiology from the produced voice, leading toward clinical and speech technology applications. Dr. Zhang is a Fellow of the Acoustical Society of America, a recipient of the Quintana Award from the Voice Foundation, and an Associate Editor and Coordinating Editor for the Journal of the Acoustical Society of America.
