In the summer semester 2020, different departments of the university launched the „Publikumspreis für exzellente Lehre“ (Audience Award for Excellent Teaching). All students of the Department of Chemical and Biological engineering had the opportunity to nominate lecturers who have distinguished themselves through particularly good teaching and innovative solution to the digitalized semester. The lecture „Grenzflächen in der Verfahrenstechnik“ (“Interfaces in Process Engineering”) by Prof. Nicolas Vogel was selected as the top choice one from the 70 nominations that students submitted. The lecture was recorded and is available on Youtube, while at the dates of the actual lecture, Nicolas held online sessions to deepen the understanding, answer questions and give room for discussions. The students also described the lecture as lively, interesting, well explained and exciting. Congratulation Nicolas!
