Tuomas Rossi

Research interests

During his time in our research group, which was funded by a Marie Skłodowska-Curie Actions individual-fellowship (MSCA-IF) from the European Research Council (ERC), Tuomas’ worked on nanoplasmonics, photocatalysis and strong coupling in nanostructure-molecule systems. In this context, he also worked on method development for time dependent density functional theory (TD-DFT) calculations.

In 2020 Tuomas returned to Aalto University on a post-doctoral fellowship from the Finnish Academy of Science.
