Riku Tuovinen

My research focuses on understanding how interacting quantum systems behave out of equilibrium, with applications in nanomaterials, optoelectronics, and quantum technologies. By developing predictive and scalable theoretical tools, such as non-equilibrium Green's functions, my work supports the modeling of quantum transport and light-matter interaction in realistic settings.
