Ashwini Joshi
Lab Director, Ph.D., CCC-SLP
Dr. Joshi’s research interests are in developing evidence-based assessments and treatments for voice disorders. The two primary foci of her current research are identifying low-cost assessment tools for voice disorders and developing an evidence-based protocol for rehabilitation after vocal fold surgery for benign lesions. A grant from the National Institute of Health allows for the measurement of patient compliance towards current post-surgical protocols.
