Research Interests

  • Establishing a metric of lingual complexity, documenting normative values of this metric in children, and determining whether it is related with treatment response
  • Efficacy of telehealth approach to acoustic biofeedback treatment delivery
  • Ultrasound and acoustic biofeedback treatment for persistent /r/ sound distortions in children and adolescent populations
  • Perception and production relations in Spanish-English bilingual children with typical development and with speech sound disorders
