PhD Candidate


Chidozie Onwudinanti holds two Master’s degrees from the Moscow Power Engineering Institute and Delft University of Technology, in Power Electronics and Sustainable Energy Technology respectively.

Dozie joined our group in March 2017. He is currently studying the hydrogen diffusion in transition metals and their alloys using atomistic modelling techniques including DFT and micro-kinetics and kinetic Monte Carlo. He is also a member of Plasma Material Interactions at DIFFER.

Dozie succesfully defended his PhD thesis in September 2021. Currently, he is working as a system engineer at ASML.
