The regularly recurring scientific seminars are intended to be an internal CeTI event where employees explain the basics of their research to their colleagues. This format has advantages for both the lecturer and the listener. The lecturer practises science communication and tries to explain his or her content to people outside the scientific community. This trains the lecturer’s ability to abstract. The audience is given the opportunity to learn more about the field of expertise of their colleagues, thus increasing the interdisciplinary nature of CeTI. New points of contact may arise. The Scientific Seminar Series is organized as PD² Colloquium.
