    Research

    My research is centered on the innovative fusion of deep reconstruction algorithms and end-to-end optics design. This involves developing deep learning models and formulating optimization strategies that incorporate optical elements into the computational loop. Focusing on the following topics:

  • Minimalistic cameras design.
  • Deep learning for optical design.
  • Computational cameras.
  • Optics-aware computational photography.
