Scientific interests
What I am interested in
I investigate how complex sounds are represented and understood, particularly when listening conditions are difficult. My work has concentrated on speech perception in noise, binaural hearing, spatial release from masking and the temporal cues that allow a listener to separate one sound source from another. I am interested in the gap between a normal pure-tone audiogram and the real-world problems that people can experience in noisy rooms. This includes the contribution of age, acoustic trauma and possible changes in peripheral and central auditory processing.
The research combines behavioural experiments, physiological measurements and quantitative models. Human data are complemented by work in Mongolian gerbils, where controlled acoustic exposure and neural recordings allow hypotheses about age-related hearing and cochlear synaptopathy to be tested more directly. Modelling is important because it makes assumptions explicit and links measurable acoustic features to predicted performance. Recent public work examines temporal fine structure, speech-sound discrimination and the neural representation of rapid fluctuations. Across these projects, the goal is to understand which auditory cues remain reliable, which become degraded, and how laboratory measures can better predict communication in realistic environments.
Why the Albert Lab
Why I joined the Albert Lab
The Albert Lab offers a direct connection between auditory perception and the mechanical and cellular processes that create auditory signals. That is valuable because behavioural performance is the final result of many interacting stages: sound transmission, receptor mechanics, neural coding, binaural integration and decision-making. Working in a group that can measure vibration, physiology and behaviour makes it possible to formulate questions that connect these stages rather than treating them independently.
Oldenburg's broader hearing-research environment also supports collaboration across animal physiology, acoustics, audiology and computational analysis. My contribution brings experience in psychoacoustics, comparative behavioural paradigms and modelling of speech intelligibility. In return, the Albert Lab provides access to mechanistic approaches that can help explain why particular perceptual effects occur. I value projects in which models are tested against carefully designed experiments and revised when they fail. The group is therefore a good setting for work that aims to translate between controlled sensory measurements and the complicated listening situations encountered by people and animals outside the laboratory.
Beyond the work
Anything else I would like to share
My public research record spans binaural speech-intelligibility models, sound localisation, speech discrimination, temporal processing and age-related hearing. A recurring theme is that hearing cannot be described adequately by thresholds in quiet alone. The auditory system must follow rapid changes, use differences between the ears and identify relevant signals in reverberation and competing noise. Comparative studies provide a useful way to isolate these mechanisms while retaining behavioural relevance.
I also value transparent quantitative tools. Publicly available work includes software for analysing auditory brainstem responses and models that turn acoustic input into testable predictions. Such resources make it easier to compare experiments across laboratories and to determine where a model succeeds or fails. The personal material on this page is a publicly informed draft and should not be interpreted as a statement about private interests that have not been shared. What can be stated confidently is a sustained professional interest in rigorous auditory measurement, realistic listening problems and the productive combination of behavioural data with mechanistic explanation.
