Research Associate in AI, Ethics, and Language at the University of Cambridge
Project Manager for the Early Career Community at the Centre for Human-Inspired AI
I have recently defended my PhD thesis at the Language Technology Lab at the University of Cambridge. I was supervised by professor Anna Korhonen and doctor Simon Baker. In my PhD thesis, I looked at the automatic detection of the signs of Alzheimer's disease from language and speech. I am interested in improving the methods of data collection and analysis, and in the ethical considerations that arise in speech- and AI-based disease detection.
