    I am a clinical researcher mainly focused on voice & its disorders and speech science.  I am interested in understanding how voice therapy works with different pathological conditions and the role of learning methods, instructions and feedback in the outcome of voice therapy. I use both subjective (perceptual) and objective (instrumental) measures to gauge the outcome of the voice therapy.
