I am the PI and Center Director of the Research Centre for Responsible Media Technology & Innovation – MediaFutures worth around 28 million EUR. I am also the founder of the DARS lab at UiB and hold a 10% senior researcher position in NORCE, one of Norway’s largest research institutions. I am also a External Lecturer at MODUL University Vienna, Austria’s leading international private university. I have received a PhD (with distinction), an MSc (with distinction) and a BSc in Computer Science and Telematics from Graz University of Technology (Austria). I am an ACM Senior Member and a former Austrian Research Promotion Agency (FFG) fellow, Marshall Plan and European Research Consortium for Informatics and Mathematics (ERICM) fellow and have been working at Graz University of Technology from 2009-2012, the University of Pittsburgh from 2011-2012, the Norwegian University of Science and Technology from 2014-2015, and have been visiting Yahoo! Labs Barcelona in 2014 and CWI Amsterdam in 2015 two times. I position my research in two central specializations in the Information Science research field. The first is “Behavioral Data Analytics” and the second is “Recommender Systems”. Since 2009, I published over 100 scientific articles in top venues about my work and have acquired over 54 million Euros in funding on European and (inter) national – 30 millions as the PI. Examples of outlets were my work has been published includes NATURE Sustainability, PlosOne, JASIST, EPJ Data Science, UMUAI, WWW, ICWSM or ACM SIGIR. I am also the winner of several Best Paper/Poster Awards and Nominations, including, the Best Paper Award Honorable Mention at the prestegious CORE A* ranked The Web Conference in 2017. I regularly act as a (senior) PC member on several top-tier – CORE A* ranked – conferences and co-organize or co-chair a number of workshops and conferences. Recent examples include ACM RecSys in 2018 – 2020 (as co-chair) and ACM SIGIR 2020 – 2021 (as senior PC). I am a steering board member of CEDAS (Center for Data Science) at UiB, a member of the study program board of the Information Science program at UiB and a member of the editorial board of Elsevier’s journal on Online Social Networks and Media, and the MDPI Open Access Journal Future Internet.
