I continue research efforts into the clinical analysis of normal and disordered voice production with particular emphasis on advanced statistical signal processing algorithms and ambulatory monitoring of daily voice use. My work bridges the areas of statistical signal processing at Harvard and clinical voice assessment at the MGH Voice Center.

My doctoral dissertation investigated the details of the relationship between the motion of the vocal folds (the "voice box") and the acoustics of voice production. My expertise is in signal processing and acoustic voice analysis, and I brought these engineering tools to clinical voice research. I implemented a comprehensive laryngeal high-speed videoendoscopy system to image (mouseover image above) and quantify vocal fold vibratory characteristics and relate them to voice-related sensor measurements and mathematical models. Further research during my postdoc involved developing a smartphone platform for tracking voice use using an accelerometer taped to the neck.

The hope is that our results will aid voice surgeons and speech-language pathologists in better understanding the mechanisms of normal and disordered voice production.
