Curriculum Vitae
Roman Schlieper received his Bachelor of Engineering degree with the specialization in communications engineering from the University of Applied Sciences Emden in 2012. For his master degree he moved to the TU-Berlin to study audio communication and -technology. During the time at TU-Berlin he completed an internship in the research department for acoustics at Sennheiser Electronics GmbH & Co. KG, where he subsequently wrote his master's thesis (2015). After a year in the automotive industry, where he worked as a systems engineer in the field of signal processing he decided to return to the university and started as a research assistant in the audio communications and -acoustics group of Prof. Peissig at the Institute of Communications Technology of the Leibniz University Hannover.
