Department of Applied Mathematics and Theoretical Physics

I am a Postdoc at the Cambridge Image Analysis group. My research interests include

  • deep learning
  • inverse problems
  • invertible neural networks
  • medical imaging (in particular high-dimensional 3D data)
  • adversarial examples
