Curriculum Vitae

JULIUS FRIEDEMANN WERNER was born in Oranienburg, Germany in 1998. He received his Bachelor of Science in Medical Engineering in 2019 followed by his Master of Science in Medical Engineering from the University of Lübeck in 2022. He wrote his master thesis in collaboration with the Turin section of the Italian National Institute for Nuclear Physics (INFN). During his studies he was mainly interested in image processing and reconstruction with a focus on particle therapy verification. Since February 2022 he is a research assistant at the Institute of Medical Engineering in the field of nuclear imaging.
