I joined the CNRS as a permanent researcher in October 2010. Since September 2014, I am a faculty member of the Computer Science Department (LIP6, APR team) of Sorbonne Université. From 2010 to 2014, I was a faculty member of the TII Team of the LTCI  lab at Telecom ParisTech. Prior to my CNRS tenure, I held a postdoctoral research associate position at the Scientific Computing and Imaging Institute at the University of Utah. I defended my Ph.D. thesis in October 2008 at the University of Lille.
My research interests include Topological Data Analysis and its applications in scientific data analysis and visualization.
I'm always looking for talented and motivated students to work with. Feel free to send me internship applications.
