Software

  • I made contributions to the Plane-Wave Density Functional Theory (PW-DFT) package DFTK in Julia language. Those include an interface with Wannier90 for Wannierization (later used to integrate the wannierization package Wannier.jl fully written in Julia language, in DFTK) and the implementation of the modified-operator method.

  • Other contributions are related to my publications and can be found on my Github
