Audiology (Au.D.)


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

Audiology Graduate Program Director/Professor

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.”

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.”

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.”


Off-Campus Preceptors

Roz R. Garfinkel, Au.D., CCC-A/F, AAA/Board Certified Audiologist
Off-Campus Clinical Preceptor


"As a preceptor, I love mentoring Towson University doctoral students to be able to 'plant the seeds' about educational audiology to a new generation of audiologists so that they will consider this branch of the field. I can provide them with experience but do not have to spend a lot of time teaching them basic skills.They come to me well prepared. I can concentrate on specializing their testing and rehabilitation skills with parents, teachers, infants, preschool children, school age / deaf / hard of hearing children, and with auditory processing testing. The motivation and enthusiasm shown by the doctoral students I have worked with bodes well for their future success in the field and reflects well on the institution that trained them. All of the students I have worked with were extremely employable and would have my enthusiastic recommendation. The faculty at Towson has been a pleasure to work with–supportive and caring. I look forward to my next semester's students."


Greg Wilson, M.S., CCC-A, FAAA Greg Wilson

Off-Campus Supervisor
President of Hearing Specialty Group, Ltd.

"My experience with the Towson Doctoral program has been very beneficial to Hearing Specialty Group. During recent years, additions to our audiology staff have been primarily Towson students. These students have been motivated to learn and motivated to provide the best services possible. Two of those students have now opened their own private practices and are destined to be very successful. The cooperation of the Towson University faculty has been exceptional."


Kimberly A. Bank, Au.D. Kimberly Bank

Off-Campus Supervisor
Senior Audiologist, GBMC Audiology

"We have had the pleasure to supervise numerous Towson University Audiology students over the years. Towson students come to our facility with a strong academic foundation and are ready to forge ahead into heavy clinical work. Several of our Towson interns have transitioned into full-time employment at GBMC and have been strong members of our GBMC team. We look forward to continuing our collaboration with both the Towson University faculty as well as their students."


W. Stephen Seipp, Au.D. Stephen Seipp

Hearing Assessment Center, Inc.
Lecturer and Off Campus Supervisor

‘Working with Towson University students both in the classroom and at the Hearing Assessment Center is a joy. The enthusiasm they bring to class and to the clinic is contagious. Working through the diagnostic mental process and watching the students connect the classroom knowledge to the ‘real world’ is an energizing process. These students are the future of Audiology and helping with their training we feel is not only our obligation but also our pleasure.”


Nancy E. Hart, Au.D., FAAA, CCC-ANancy E. Hart, Au.D., FAAA, CCC-A
Healthy Hearing and Balance, Ltd.

"As a graduate of the Towson Au.D. program it is such a thrill to be able to share my experiences with the current Au.D. students. Whether giving a guest lecture, talking about the process of setting up a private practice or mentoring students I find that I get as much out of the experience as the students do. That's the joy of sharing. It is an express goal of mine to mentor audiology doctoral students who are interested in private practice ownership, especially young women. This is an incredibly wide open field and the sky's the limit for people who are motivated and dedicated to the profession."


Matt Perry, Au.D.Matt Perry
Off-Campus Supervisor
Owner of Harmony Hearing & Audiology

“Working with the students and staff at Towson University has been a very enjoyable and mutually beneficial experience. The students that have worked in my office have been exceptionally well prepared. My patients have enjoyed their presence so much that they’ve started to complain when they’re scheduled with ‘just Dr. Perry’ between semesters. They’ve really been a great addition to our practice. As a practicing audiologist and off-campus supervisor, I love having the opportunity to inspire and teach the next generation of clinicians while serving those in need.”
