Jouko joined the group in 2020 to study and improve water potentials for molecular dynamics and extend them to include ions with machine learning techniques. He has previous experience in first-principles modeling of solid-state matter. He pursued a doctorate under the supervision of Prof. Patrick Rinke at Aalto University, where his dissertation focused on kinetic energy functionals and semiclassical approximations used in density functional theory. He also studied wide band-gap semiconductors, mainly gallium oxide. He has a master’s degree in Mathematics from Aalto University.
