TECH Talks

René Gifford, Ph.D., is a professor of hearing and speech sciences at Vanderbilt University Medical Center in Nashville, TN. In her lecture at CI2018 in Washington DC, Dr. Gifford spoke about electrode options for cochlear implant patients and how they apply to today’s modern cochlear implant candidates.

As a world-renowned scientist, Dr. Gifford covers the importance of challenging the status quo through following current research and a complete list of the peer-reviewed publications she references appears at the end of the TECH Talk.

Hear directly from Dr. Gifford about Vanderbilt University’s electrode preferences, the importance of perimodiolar placement in scala tympani and her lab’s current work on how number of channels can positively impact patient performance.
