Reading pain in children’s faces

Young children often cannot say how much pain they are in. In the Department of Paediatric Surgery at LMU University Hospital Munich I build the AI that helps staff read it from their faces.

What I build

  1. A model that reads pain

    A computer vision model in Python and PyTorch that estimates children’s pain from facial expressions, from clinical need to working prototype.

  2. Data where there is none

    Paediatric facial pain data is scarce, so I designed a diffusion-based pipeline that generates synthetic training images.

  3. A tool clinicians use

    I owned the end-to-end build of a web-based, human-in-the-loop annotation platform for 50+ clinical experts.
