Short bio

After studies in chemistry oriented towards experimental materials science I moved to theoretical chemistry for my master 2 and my PhD. As an intern in different groups I had the opportunity to work in different groups on the synthesis, shaping and characterization of polymers, mineral single crystals and carbon nanotubes. My daily work now implies ab initio molecular simulations of nanomaterials/water interfaces using static DFT and DFT based molecular dynamics, and to perform data analysis via writing of scripts in Python and Fortran.
