02-Mar-2022 Doctoral theses awards
Antti Moilanen, who joined our group late in 2021 just received an award for outstanding PhD thesis at Aalto University, Finland. Antti’s PhD thesis “Bose-Einstein condensation in plasmonice lattices” demonstrated the first Bose-Einstein condensate of plasmonic quasiparticles. The criteria for the award were the academic quality, impact, and originality of his thesis.
Two weeks earlier, Felix Tebbenjohanns was awarded with the ETH medal for an outstanding doctoral thesis. His work was performed in the Photonics Lab on "Linear Feedback cooling of levitated Nanoparticle in free space". The official ceremony took place in person at ETH on January 17, and Felix received his award personally by the president Joël Mesot himself.
CONGRATULATIONS to both!!
