About my research
I have always been fascinated with the intersection of music, sound, science, and engineering. This passion guided me to follow an academic career devoted to studying these disciplines in an interdisciplinary manner for researching voice disorders and voice production using tools from Biomedical Engineering, Acoustics, and Audio Signal Modeling and Processing.
Currently, I am working on validating clinically relevant data captured from a tiny accelerometer situated over the neck skin to obtain approximations of the glottal airflow for objectively assessing vocal function. I also work in music technology and audio/acoustic research, developing applications for audio production, audio transducers, loudspeaker enclosures, and room acoustics applications.
