Dr. Xu’s primary research interests include tissue engineering of the vocal fold, anatomy and physiology of voice production, and laryngeal biomechanics. His current project involves the development and testing of a vocal fold lamina propria tissue replacement for surgical applications. 

The future research plans of Dr. Xu’s lab revolve around the development of materials for vocal fold engineering and reconstruction. The complexity of the human vocal fold and the various possible tissue engineering approaches make this a rich topic with many challenges to be resolved.
