Kathryn Arehart, Ph.D. CCC-A, Professor (University of Washington)
Dr. Arehart’s primary area of expertise in both teaching and research is audiology and hearing science. She is head of the Hearing Research Laboratory. The laboratory’s research focuses on understanding auditory perception and the impact hearing loss has on listening in complex auditory environments. Current research projects include the effects of hearing loss on pitch perception, signal-processing algorithms to improve speech-in-noise perception by persons with hearing loss, perception of sound quality, and the interactive effects of aging and hearing loss on speech perception. These research projects include interdisciplinary collaboration with colleagues in engineering, psychology, and cognitive science. Professor Arehart teaches undergraduate and graduate courses in speech and hearing science and audiology and leads outreach workshops for K-12 teachers on teaching children about sound, hearing and hearing health. She is also a certified clinical audiologist. Email

Judy Brooke received her B.A. in Communication Disorders from Pacific University in Oregon, in 1981, and her M.S. in Speech-Language Pathology from Idaho State University in 1998.   She has worked with children of all ages, families, and young adults in a variety of educational and medically-based clinical contexts.   As a speech-language pathologist, she has provided diagnostic and intervention services in early intervention settings, bilingual and monolingual preschools, out-patient rehab clinics, centers for individuals with developmental disabilities, and many school districts.  Her areas of specialization and interest include child language, child speech, childhood apraxia of speech (CAS), bilingual development and child development within culturally and linguistically diverse contexts, collaborative-integrated therapy, literacy and writing skills, and the adult (clinician) learning process of integrating knowledge with experience through critical reflection.  Email
Tammy Fredrickson, Ph.D., CCC-A, Assistant Clinical Professor (University of Colorado Boulder)
Dr. Fredrickson works with AuD students both as a clinical supervisor at the University of Colorado Hospital Department of Hearing and Balance and as Director of Audiological Services. As Director of Audiological Services, she coordinates practicum experiences for audiology graduate students and ensures that the AuD program continues to meet the high standards of accreditation. She received her BS (1996) and MS (1998) from the University of Wisconsin Stevens Point and her PhD from University of Colorado Boulder in 2010.
Dr. Fredrickson’s primary area of interest is infant speech perception. She has worked with colleagues to develop a clinical tool to assess infants’ abilities to discriminate speech sounds: Visual Reinforcement Infant Speech Discrimination (VRISD). University of Colorado Hospital now uses this tool regularly as a component of their test battery when working with infants with hearing loss. Recent and future VRISD studies include investigating the development of infant speech perception and how an infant’s ability to discriminate speech sounds relates to physiological changes as well as language abilities. Other areas of interest include auditory processing testing and rehabilitation and clinical supervision.
Dr. Fredrickson holds the Certificate of Clinical Competence from the American Speech-Language-Hearing Association and is a Fellow with the American Academy of Audiology. Email

Willy Moers, Instructor
Instructor Moers teaches all levels of American Sign Language (ASL) and has also taught an anthropological course entitled Ethnography of the (American) Deaf Community. A native ASL signer by birth, he comes from four generations of culturally Deaf families. A globetrotter, fly fisherman and skier by interest, he has also participated in many summer Deaf Olympics in the hammerthrow and discus events, an experience which is not only competitive but also culturally rich. He graduated from Gallaudet University, which is the only liberal arts college in the world for deaf students. He brings a rich cultural perspective to his teaching, where students not only learn ASL, but about the complex and historic deaf culture. His favorite quote is by George Veditz, one of the early presidents of National Association of the Deaf, “As long as we have deaf people, we will always have sign language.” E-mail

Anu Sharma, Ph.D., Professor (Northwestern University)
Professor Sharma’s research focuses on the effects of auditory deprivation on cortical development, re-organization and cross modal plasticity in children with hearing impairment. Dr. Sharma and her research team are conducting studies using cortical auditory evoked potentials in normal-hearing children, hearing impaired children fitted with cochlear implants & hearing aids and children with auditory neuropathy. She directs the state-of-the-art Brain and Behavior Laboratory where students perform auditory electrophysiology testing including auditory brainstem response, middle latency response, cortical potentials, high density electroencephalography (EEG) in response to auditory and multisensory stimulation. She has recently started incorporating  magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) techniques in her research. Dr. Sharma also directs a clinical laboratory located at the University of Colorado Health Sciences Center in Denver where she is performing research to assess the sensitivity of cortical potentials as clinical biomarkers to determine the maturational status of the central auditory system in hearing impaired persons.

Christine Yoshinaga-Itano, Ph.D., CCC-A, Professor (Northwestern University)
Dr. Yoshinaga-Itano is both a teacher of the deaf and hard of hearing and an audiologist.  She has conducted research in the areas of language, speech, and social-emotional development of deaf and hard-of-hearing infants and children for over thirty years.  Her research has been funded by the National Institutes of Health, the Office of Education, Maternal and Child Health, the Center for Disease Control, the Colorado Department of Public Health and Environment, the Colorado Department of Education, and the University of Colorado.  Over the last 20 years, she has focused on the impact of early-identification and early intervention on the developmental outcomes of children with significant hearing loss.  Professor Yoshinaga-Itano was the first to demonstrate that when infants with hearing loss are identified in the first few months of life and provided with appropriate intervention services, that 80% these infants/children with significant hearing loss and no additional disabilities are able to maintain age-appropriate language development and intelligible speech in the first five years of life.  As a result of this research, universal newborn hearing screening programs were implemented in the United States.  The only other newborn screening mandated in the United States is screening for phenyketonuria (PKU).   Professor Yoshinaga-Itano’s research demonstrated that it was critical that identification of hearing loss and early intervention must occur within the first six months of life in order for the majority of children with congenital hearing loss to maintain language development commensurate with their normal hearing peers, indicating that there is a sensitive period of communication development that requires access to language development early in life.  She also studies the development of infants/toddlers and children with hearing disabilities in non-English speaking homes.  The impact of early identification and intervention on successful outcomes of children with hearing loss was found irrespective of the socio-economic status of the families, the method of communication, the race/ethnicity of the family/child, or the gender of the child.  As a direct result of her research studies, universal newborn hearing screening programs have now been implemented in all 50 states and also in many countries throughout the world, including the United Kingdom, Canada, Australia, Japan, Poland, and Brazil.  Lab website.  Email
