Jean-François Baffier is an academic researcher at the Graduate School of Information Science and Technology of The University of Tokyo. As an academic, he gives back to society through fundamental research in computer science supplemented by open-source libraries and software.

Jean-François graduated from Master course at University Paris-Sud and got his Ph.D. from the University of Tokyo. He was a member of the ERATO Kawarabayashi Large Project in Tokyo and Sendai, a JSPS-CNRS research fellow hosted at the Tokyo Institute of Technology (Japan), and a postdoctoral researcher at the RIKEN Center for Advanced Intelligence Project (AIP). He also was a JFLI member from October 2011 to August 2018.

His current research project involves the study of the “Analysis of information networks,” the “Smart compression for high-scalability of data structures,” and “Explainable Artificial Intelligence.” Other topics of interest covers modeling of failures and routing in Networks, Game Analysis, and AI for Games.

Jean-François implemented the StaticWebPages.jl package to generate this website using a simple content file. Stay tuned to the Humans of Julia's Discord server for more software related to the Modern Academics project.
