Since Decembre 2019, I am a postdoctoral researcher advised by Jean-Daniel Fekete in the Aviz team of Inria, also part of Université Paris-Saclay.

I am interested in information visualization, network visual analysis, and interactions. I am especially interested in designing scalable techniques or systems that enable interactive exploration of large or complex datasets.

I am looking for a postdoc starting from Spring 2023. Reach me by email.
