AI, NLP and digital medicine

Validating and critically discussing AI, NLP and digital tools in psychiatry is my main research focus. I currently work on examining ethical and regulatory implications of developments in digital medicine and the longitudinal validation of AI-based speech analysis in psychosis and across multiple languages. I am also more broadly interested in the use of digital technology for improving the treatment of people with serious mental illness, e.g. through virtual reality applications.
