Nicolas Vannson

Hearing Data Scientist · PhD in Auditory Neuroscience

I'm a former audiologist who moved into data science to turn clinical complexity into actionable intelligence. After more than a decade working with hearing-impaired patients and leading quantitative research, I founded Hearing Data Science in 2025 to help audiology organizations improve patient care through advanced analytics, machine learning, and AI-driven decision support.
