Dr. LaGuinn Sherlock is a research audiologist with over 30 years of clinical and research experience. She serves as a Hearing Program Studies Investigator for the Defense Center for Public Health – Aberdeen, based at Walter Reed National Military Medical Center.

Her research focuses on tinnitus prevalence in the military, screening and management protocols, and cognitive measures of tinnitus impact. 

Dr. Sherlock was the DOD co-champion for the VA/DOD Clinical Practice Guideline for tinnitus and has been recognized for her contributions to hearing science by the Military Audiology Association and the U.S. Army Public Health Center.

A former chair of the American Tinnitus Association Board of Directors, she currently serves on the ATA’s Scientific Advisory Committee and as a tinnitus advisor. Dr. Sherlock also helped develop ATA’s Tinnitus Advisors Program, supporting individuals with tinnitus through education and guidance.

Dr. Grant Searchfield is a professor of audiology and head of the audiology section and department at the University of Auckland's Faculty of Medical and Health Sciences. His research focuses on cognitive processes in tinnitus perception and innovative technologies for managing hearing loss and tinnitus.

He is also the director of the Faculty Research Centre, Eisdell Moore Centre for hearing and balance research, and a primary investigator at the Centre for Brain Research and Te Tītoki Mataora, New Zealand's MedTech Research Translator.

He serves as specialty editor for Frontiers in Audiology and associate editor for Frontiers Auditory Cognitive Neuroscience. He is also the scientific director of TrueSilence Therapeutics Inc.

Dr. Bruce Hubbard is a clinical psychologist and expert in cognitive behavioral therapy (CBT) for tinnitus. After developing severe tinnitus distress in 2005, Dr. Hubbard successfully applied CBT to his own recovery and founded CBT for Tinnitus, LLC, to provide online coaching for individuals with tinnitus distress and educational resources for professionals worldwide.

A visiting scholar at Columbia University, Teachers College, and a past president of the New York City Cognitive Behavior Therapy Association (2016–2018), Dr. Hubbard also serves on ATA’s Scientific Advisory Committee. His webinar, Cognitive-Behavior Therapy for Tinnitus, sponsored by the Anxiety & Depression Association of America (ADAA), has garnered over 400,000 views.

Dr. Hubbard earned his doctorate in Clinical Psychology from Binghamton University and completed his clinical internship at New York University Medical Center, Bellevue Hospital.

Dr. Marc Fagelson is a professor of audiology at East Tennessee State University. In 2001, he opened the James H. Quillen Veterans Affairs Medical Center (VMAC) Tinnitus Clinic that now enrolls more than 1,300 patients. In July 2023, Dr. Fagelson was voted 

chair of ATA’s Scientific Advisory Committee (SAC), responsible for coordinating applications for the ATA’s Innovative Tinnitus Research Grants program. These applications are reviewed and recommended by SAC’s 28 leading international researchers, with final funding decisions made by the ATA Board of Directors each grant cycle.

Dr. Fagelson co-edited with Dr. David Baguley two texts published by Plural that center on tinnitus and disorders of sound tolerance. He has more than 50 publications and has given more than 100 conference and workshop presentations. He received a BA in English and MS in audiology from Columbia University, and his PhD in hearing science from the University of Texas at Austin.

Dr. Robin Guillard is a postdoctoral researcher specializing in tinnitus, focusing on the interactions between tinnitus and sleep and tinnitus heterogeneity. In 2024, he received an ATA Innovative Tinnitus Research Grant, supporting his investigation in France on how sleep impacts tinnitus.

Originally trained as an engineer, Dr. Guillard transitioned into entrepreneurship and neuroscience, founding Zeta Technologies to develop solutions for tinnitus. Although the startup’s clinical trial didn’t succeed, the experience underscored the need for more research.

He also co-founded Siopi, a platform supporting tinnitus patients, collecting data, and promoting clinical trials. Through research and patient-centered innovation, Dr. Guillard strives to improve understanding and care for those with tinnitus.

Ken Rawling, a trial participant, experienced sudden-onset tinnitus in his right ear in April 2015. Applying his expertise in statistical methods and experimental design, he conducted a single-subject research project that identified sleep quality—not quantity—as a significant factor influencing his tinnitus perception. 

In spring 2023, Mr. Rawling presented his findings at the Tinnitus Research Initiative conference in Dublin, where he met Dr. Robin Guillard. The two have been collaborating ever since to better understand the interactions of sleep and tinnitus.

Brought to you by Tide Project principal investigators Christopher Cederroth, PhD, Julia Campbell, AuD, PhD, Fatima Husain, PhD, and Rebecca Lewis, PhD, as moderator.  

Discover how the TIDE Project – an international consortium of leading researchers – is seeking to transform tinnitus care through cutting-edge research. Join three of the seven principal investigators as they discuss efforts to identify tinnitus biomarkers and develop a data-driven, personalized approach to diagnosis and treatment. 

Their goal: Replace the current “trial and error” approach to tinnitus interventions with an objective, clinically applicable tool that improves outcomes for those with chronic tinnitus.
