Biography
Johann Riemensberger is a postdoctoral scholar at EPFL in the group of Tobias Kippenberg at the Laboratory of Photonics and Quantum Measurements. He currently holds a Marie-Curie Induvidual Fellowship and researches on ultrashort pulse generation using photonic integrated soliton microcombs and their applications for laser ranging experiments (LiDAR). He received his Diploma in Physics from the Technical University of Munich, preforming his thesis project at EPFL in the group of Tobias Kippenberg on CMOS-compatible optical frequency comb generation in 2012. He obtained his PhD in Munich under the supervision of Reinhard Kienberger on Time- and Frequency-resolved measurements of absolute photoemission time delays in 2018, which was awarded the dissertation prize of the "Bund der Freunde der TUM". He since returned to EPFL holding a Marie Skłodowska-Curie Individual Fellowship.Education
