J.H.M. Frijns

Professor J.H.M. Frijns serves at Delft University of Technology within the Faculty of Electrical Engineering, Mathematics and Computer Science, leading research in the Bio-Electronics department. His work bridges biomedical engineering and clinical audiology to advance hearing rehabilitation technologies, particularly cochlear and auditory brainstem implants.

His research spans cochlear implant optimization, pupillometry-based listening effort measurement, neuroanatomical analysis of genetic hearing disorders (e.g., Labyrinthine Aplasia, Microtia, and Microdontia syndrome), and quality-of-life outcomes. Key contributions include establishing pupillometry as a physiological marker for cognitive load during speech processing and investigating societal participation changes throughout cochlear implantation timelines.

Recent publications (2024-2025) reveal a strong interdisciplinary trend: integrating neuroscience (pupillometry metrics), genetics (FGF3 gene defects), and patient-centered outcomes (quality of life, communication partner dynamics) to move beyond pure audiometric measures toward holistic rehabilitation assessment. This work frequently employs comparative test methodologies and longitudinal observational designs.

As a core member of TU Delft's Bio-Electronics research group, Professor Frijns collaborates extensively with ENT departments and rehabilitation centers, focusing on translating engineering innovations into clinical practice for hearing impairment solutions.
