Audiology (Au.D.)


Jennifer Smart, Ph.D., CCC-AJennifer Smart, Ph.D., CCC-A

Graduate Program Director

Dr. Smart’s professional interests include auditory processing disorder (diagnosis and intervention in adults and pediatrics), auditory neuropathy/dys-synchrony, and electrophysiological assessment of special populations, efficacy of personal FM systems for children with auditory processing disorder (APD), test-retest reliability of APD in adults, reported benefits and use of personal FM systems for children with APD, and diagnosis and treatment of APD in adults. Some of her recent achievements include a fellowship and equipment grant funding and invitations to be the keynote speaker at several national conventions.


Diana C. Emanuel, Ph.D., CCC-A Diana Emanuel, Ph.D., CCC-A
Chair, Department of Audiology, Speech-Language Pathology and Deaf Studies

Dr. Emanuel's professional interests include hearing science, auditory processing, and pedagogy in Communication Sciences. She recently published a hearing science textbook.

“Learning is a partnership between teacher and student — the teacher should share their experiences in a way that transmits their passion for the subject and the student should bring a desire to learn that extends beyond the walls of the classroom.”



Peggy Korczak, Ph.D., CCC-A Peggy Korczak, Ph.D., CCC-A


Dr. Korczak’s professional interests include electrophysiology, central auditory processing, and otoacoustic emissions. Some of her recent achievements include a 2008 publication in Ear and Hearing on speech-evoked potentials and a 2002 Ear and Hearing article on cortical evoked potentials that was voted “the most thought provoking article for 2002” by the Hearing Journal.

“I had to laugh when I read one of my students commented that ‘Dr. Korczak knows Auditory Brainstem Response (ABR) testing so well that I think she invented it.’ My philosophy in teaching several of the advanced diagnostics classes, such as electrophysiology I and II as well as vestibular assessment and rehabilitation is to use both didactic instruction as well as hands-on labs. The small group lab exercises and follow up reports for these classes really help cement the theoretical principles and provide an opportunity for the students to gain confidence in setting up, administering and interpreting these procedures.”

Amanda N. Kozlowski, Au.D., CCC-AAmanda N. Kozlowski, Au.D., CCC-A

Audiology Clinic Director

Dr. Kozlowski’s professional interests include vestibular testing, hearing instruments, cochlear implants and clinical supervision of graduate students.

“I enjoy helping students bridge that gap between the classroom and the clinic. It’s such a rewarding experience when students make those connections.”

Stephen Pallett, Au.D., CCC-AStephen Pallett, Au.D., CCC-A

Clinical Assistant Professor

Dr. Pallet’s professional interests include hearing aids, calibration, and electrophysiology. His recent achievements include a chapter in a hearing science textbook.



Saradha Ananthakrishnan, Ph.D.Saradha Ananthakrishnan, Ph.D.

Assistant Professor

Dr. Ananthakrisnan's professional interests include neural plasticity in the auditory system, recording cortical event-related potentials in normal hearing and hearing impaired populations, and the relationship between cortical and subcortical evoked potentials, statistical modeling of various demographic, behavioral and electrophysiological factors and sensorineural hearing loss, and characterization of the subcortical human frequency following response to varied speech signals in normal hearing sensorienural hearing impairment.


Elise Smith, Au.D., FAAA, CCC-AElise Smith, Au.D., CCC-A

Clinical Assistant Professorr

Dr. Smith's professional interests include: vestibular assessment and rehabilitation, adult and pediatric amplification, electrophysiology, auditory diagnostics and clinical supervison of graduate students.



Adjunct Faculty and On-Campus Supervisors

Tomasz Letowski, Ph.D., Sc.D. Tomasz Letowski, Ph.D, Sc.D

Thesis Advisor

Dr. Letowski currently mentors students as a member of Au.D. thesis committees in the areas of acoustics and psychoacoustics.


Thomas Coccagna, Au.D., CCC-A Thomas Coccagna, Au.D., CCC-A

On-Campus Supervisor

Dr. Coccagna’s professional interests include clinical supervision of graduate students, hearing aids, and working with the geriatric population. In addition to supervising at Towson University, Dr. Coccagna is President of Hearing Health Services, a full-service private Audiology practice, with offices in Bel Air and Baltimore.




Bette Stevens, Au.D., CCC-A

Bette Stevens, Au.D., CCC-A

On-Campus Supervisor

Dr. Stevens professional interests include pediatric/educational audiology, and children who are multi-disabled. She was the Audiology Clinic Administrator for many years at Towson University, before retiring and coming back as a part-time clinical preceptor to continue to teach students.

“One of the most rewarding aspects of my time as the Audiology Clinic Administrator was, and still is, meeting former students, now professionals, at conferences and knowing that I had a part in their professional development.”
