Mr.Thilina Senaviratne started his studies in Physics and Mathematics at the University of Peradeniya, and later switched the fields and graduated in Electrical Engineering from Riga Technical University in 2014. He then spent a year in Finland for postgraduate studies in photonics at the University of Eastern Finland. After receiving a scholarship from the French government to study at the Ecole Polytechnique, he switched back to Atomic, Molecular and Optical physics.  He graduated in 2017 with a M.Sc. in physics for Optics and Nanoscience, with his M.Sc. thesis work carried out at the Laboratoire Kastler-Brossel. Then, he joined the Physics Institute of the University of Freiburg as a researcher, where he developed a cold He atom beam source and a laser system for the optical pumping of Li atoms in a MOT with the aim of studying cold collisions of atoms. In 2019, he started his Ph.D. work at the University of Bonn, which focused on the development of an experiment to cool and trap Ytterbium atoms to study Rydberg physics.  In August 2024, he joined the Faculty of Technology, University of Sri Jayewardenepura  as a Lecturer in Physics at the Department of Science for Technology.
