Uroš Delić, born in Belgrade, Serbia, in 1987, studied physics at the University of Belgrade and the University of Vienna and computer science at the Faculty of Computing of the Union University in Serbia. During this time, he was an intern at IQOQI Vienna and worked in the group of Prof. Vladan Vuletić at MIT. He later joined the group of Prof. Markus Aspelmeyer at the University of Vienna for his Master's and PhD studies, working on cavity cooling of optically levitated nanoparticles. He was a fellow of the Doctoral program "Complex Quantum Systems" (CoQuS) and acted as a student speaker between 2013 and 2015. In 2018, he was the recipient of the Austrian Marshall Plan Scholarship for a research visit to the group of Prof. Vuletić, where he worked on cavity cooling of Cesium atoms by coherent scattering. Back in Vienna, he applied the cooling technique from atomic physics to trapped silica nanoparticles that led to the first demonstration of the motional quantum ground state cooling of a single levitated nanoparticle. He defended his PhD with distinction in 2019, receiving the Award of Excellence from the Austrian Federal Ministry of Education, Science and Research. He continued working as a University Assistant in the Aspelmeyer group and became a Senior scientist in 2023. In 2024, he received the prestigious START Prize from the Austrian Science Fund with an endowment of 1.2 million Euros toward his research. He is a group leader at TU Wien since 2025.
