Richard Dowell

Dowell, working with Blamey and others, established factors predictive of outcomes for adults who received cochlear implants. This study was followed up in 2013 by Blamey and Dowell, with other colleagues, who collected data for 2251 adults who used cochlear implants to study the factors affecting auditory performance. The study found that the history and duration of hearing loss, age and other factors were associated with cochlear implant outcomes, but that no single factor had good predictive power.

In 2006, Dowell with PhD student Mansze Mok, published a study to address the use of cochlear implants in conjunction with conventional hearing aids in the opposite ear. The study showed that acoustic hearing can provide complementary information to that provided by a cochlear implant and thus improve speech understanding.

At the University, Dowell was appointed as Head of the Department of Otolaryngology from 2005 till 2011, and for the Department of Audiology and Speech Pathology from 2012 till 2018.

In the mid-2000s, Dowell, with colleague Shani Dettman and others, studied the risks and benefits regarding the communication development of children who received cochlear implant surgery before 12 months of age. The study showed that spoken language acquisition for deaf children depended significantly on access to auditory input in their first year.

Dowell has been involved in research into auditory neuropathy with colleague Gary Rance, that established the diagnostic and management procedures for this distinct type of hearing loss identified in the late 1990s.

Dowell has conducted significant research on hearing impairment, particularly in relation to cochlear implants. He contributed to the development of many of the clinical procedures in the cochlear implant field and to signal processing improvements for these prostheses. Dowell was a key contributor to the first successful FDA approval of multi-channel cochlear implants in adults (1985) and children (1990).

Dowell then devised the initial clinical trial of the first commercial multichannel cochlear implant resulting in FDA approval for adults with profound hearing loss in 1985.

Dowell began his career as a Research Audiologist at the University of Melbourne Department of Otolaryngology in 1980 before being promoted to Lecturer of Audiology in 1989 and to Senior Lecturer in 1991. In 1995, Dowell was promoted to Associate Professor and then Professor of Audiology from 2001 till 2013. He was appointed the Graeme Clark Chair in Audiology and Speech Science in 2013.

After completing his initial studies at Carey Baptist Grammar School, Dowell studied at the University of Melbourne where he completed his Bachelor of Science in 1977, Graduate Diploma in Audiology in 1979, Masters in Audiology in 1989 and his Doctoral studies in 1991.
