Research Interests

Dr. Hebda is focusing her research on three main areas: wound healing and tissue engineering for applications in the head and neck, which aims to develop new, biologically-driven therapeutic modalities to promote and optimize wound healing of the upper digestive system; pathogenesis of inflammation in otitis media, which focuses upon understanding the molecular signaling associated with mucosal inflammation using animal models of acute otitis media, otitis media with effusion (induced by Eustachian tube obstruction), and chronic suppurative otitis media; and, applications for improving wound care and enhancing healing, which posits that the development of fibrosis can be prevented by blunting early wound-healing events leading to fibroblast recruitment and activation of their synthetic properties.
