Associate Professor DI Dr Christoph Trattner, BSc


Dr. Christoph Trattner is working as an Associate Professor (permanent position) at the University of Bergen in the Information Science & Media Studies Department. Previously to that he was an Asst. Prof. at MODUL University Vienna in the New Media Technology Department and a manager at the Know-Center, Austria's research competence for data driven business and Big Data analytics where he founded and led the Social Computing department.

Christoph holds a PhD (with distinction), an MSc (with distinction) and a BSc in Computer Science and Telematics from Graz University of Technology (Austria). He is a former FFG, Marshall Plan and ERCIM fellow, funded by the Austrian Research Promotion Agency and the European Research Consortium of Informatics and Mathematics, and has been working at Graz University of Technology from 2009-2012, the University of Pittsburgh from 2011-2012 (hosted by Prof. Dr. Peter Brusilovsky), the Norwegian University of Science and Technology from 2014-2015 (hosted by Prof. Dr. Kjetil Nørvåg), and has been visiting Yahoo! Labs Barcelona in 2014 and CWI Amsterdam two timed in 2015 (hosted by Prof. Dr. Arjen De Vries).

Christoph's research lies in two central specializations in the information science research field. The first is “Behavioral Analytics”, and in particular “Online Behavioral Understand & Modeling”, and the second is “Intelligent Information Systems” development with a focus on “Recommender Systems”. Currently, he is leading an international research effort that aims to understand online food information behavior and to potentially change this behavior through recommender technology to tackle health-related food issues such as diabetes or obesity.

Since 2010, Christoph published two books and over 90 scientific articles in top venues and journals, e.g., JASIST, UMUAI, TiiS, ComCom, EPJ Data Science, WWW, ICWSM, ACM SIGIR, ACM CIKM, ACM CSCW, ACM RecSys, ACM IUI, ACM HT and ACM UMAP. He is the winner of several Best Paper/Poster Awards and Nominations, including the Best Paper Award Honorable Mention at the very prestigious World Wide Web Conference (WWW) in 2017.

Christoph regularly acts as a PC member in several top-tier - CORE A* ranked - conferences and co-organizes or co-chairs a number of workshops and conferences. Recent examples include ACM IUI’19, ACM UMAP’19 and ACM RecSys’19. He also teaches a series of courses in the context of his two specializations such as, for example., INFO110 - Information Systems and INFO345 - Recommender Systems at the University of Bergen.
