Uroš Delić, born in Belgrade, Serbia in 1987, studied physics at the University of Belgrade and the University of Vienna. During this time, he was an intern at IQOQI Vienna and has 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 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, for which he received 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 has since become a Senior scientist.
