Marina's research interests are related to the evaluation of hearing aids for people with high-frequency hearing loss, including those with extensive high-frequency dead regions. She has conducted trials using frequency-lowering prototype and commercially available hearing aids. Her current project seeks to identify the number of amplitude-compression channels required to optimise performance with hearing aids. This project is funded by the H. B. Allen Trust. Additionally, she collaborates with Dr Josephine Marriage (Chear Ltd) and a multidisciplinary group looking at alternative interventions during the watchful waiting period in children with chronic otitis media with effusion (?Bone Conduction in Glue ear?

Dr Marriage and Marina were recently awarded the British Society of Audiology Applied Research Grant in honour of Stuart Gatehouse in support of the group?s project (October 2015).
