Campus Aiguillettes, F-54000 Nancy, France.

I am a postdoctoral researcher with SiMul research group at Université de Lorraine, France, working with Dr. Ricardo Borsoi.

Before that, I obtained my Ph.D. in Electrical Engineering in 2024 at Laboratoire Lagrange, Université Côte d’Azur, France, under the supervision of Prof. Cédric Richard. I received my master degree in 2021 under the supervision of Prof. Jie Chen, from Northwestern Polytechnical University, China, where I also received my bachelor degree in 2018.

My research interests lie at the intersection of statistical signal processing and machine learning, with special attention to

  • Riemannian optimization
  • Change point detection
  • Hyperspectral imaging

A formal biography is available here.
