Benedikt Loepp, M. Sc.

While studying the bachelor program of Applied Computer Science at the University of Duisburg-Essen, Benedikt Loepp started to work as a student assistant in 2010, among others, in the Interactive Systems group. After having received his bachelor’s degree in 2011, Benedikt joined the group as a researcher in March 2012. Since then, he has been administrative coordinator for Computer Science in the MINTroduce project, supporting study beginners at the university and being responsible for the program’s preliminary courses.

After he finished the university’s master program of Applied Computer Science in 2013 (with distinction), he finally became a full member of the Interactive Systems group. His research focuses on the field of recommender systems, in particular, preference elicitation and interactive recommending approaches. Besides, Benedikt was involved in the ColognE-mobil project part II, where he was responsible for developing smart navigation solutions for intermodal mobility chains. Furthermore, he contributed to several research developments, e.g. Blended Recommending, TagMF, and the Archaeological Sandbox. He also enjoys his teaching activities, including, among others, a lecture on Recommender Systems.

Since 2014, Benedikt is webmaster of the official ACM RecSys website, and regularly serves as web chair for the conference.
