Understanding how information from the left and right ear is combined
The brain has an amazing ability to combine information from the left and right ear. This is critical for being able to locate where sounds came from and can be very helpful when trying to listen in noisy environments. This research focuses on understanding the requirements and limitations that determine when signals from each ear will be combined.
Developing techniques to improve bilateral cochlear implant users' performance
In recent years, patients have begun receiving two cochlear implants. Although this has yielded improvements in performance, the benefits that patients receive from having two cochlear implants are considerably less than the benefits that people with two acoustic ears receive. This research focuses on improving the benefits of having two cochlear implants as well as developing novel techniques for cochlear implant patients that take advantage of the availability of two ears.

Ph.D. (Principal Investigator)
My research focuses on bilateral cochlear implant patients and binaural hearing. The goal of this research is to develop a greater understanding of how signals presented to the ears are combined and to use that knowledge to develop new techniques and technologies to improve bilateral cochlear implant patients’ performance.
I am a first year Ph.D. student with an interest in Binaural Fusion in cochlear implants. My specific interests lie in interaural timing differences within cochlear implant recipients. After working here as an RA for two years here, I realized I wanted to enhance my knowledge further into learning about cochlear implants through pursuing a Ph.D.
My research focus is on bilateral cochlear implant user's performance and perception. Specifically how a cochlear implant user’s perception of a sound affects their production of this sound. I am also interested in the effects of bilateral differences on binaural abilities, and plan to pursue this line of research.
My research interest relates to the adaptation of binaural cues in mismatched speech, particularly in bilateral cochlear implant users. I have a bachelor's degree in biomedical engineering, so I felt that research pertaining to one of the most advanced hearing technologies would complement my previous studies as well as advance my goal of becoming a research professor. I'm also interested in the clinical aspect of Audiology and can't wait to apply research findings within the clinical realm and vice versa. I find that Illinois' Audiology program is quite versatile, seamlessly balancing clinical work with research-oriented studies.
I am currently in my second year of the Doctor of Audiology program. I became interested in cochlear implant research after completing my bachelors degree in Communication Sciences and Disorders. My current research involves comparing interaural level differences and interaural time differences between normal hearing listeners and patients with bilateral cochlear implants. I plan on pursing a career in clinical research with cochlear implants after completing the Au.D program.
I am a senior in the department of Speech and Hearing Science and aspire to become a Speech Language Pathologist. After completing my education, I hope to work for a nonprofit organization or medical mission team and use my skills to help those in third world countries. I have been with the Binaural Hearing Lab since Fall 2014 and have thoroughly enjoyed learning more about hearing science and cochlear implant research.
Hi! I'm Melanie Samuels and I'm a sophomore majoring in Speech and Hearing Sciences with a concentration in Audiology. I became interested in this field after learning about cochlear implants in a high school psychology class, and I've been hooked ever since. I love working in the lab because I get to do things that I didn't think I would get to do until I was a practicing audiologist!
