Short BIO

Dr. Christoph Trattner is currently working as an Asst. Prof. at MODUL University Vienna in the New Media Technology Department. Previously to that (2013-2016) he was an area manager at the Know-Center, Austria's research competence for data driven business and BigData analytics where he founded and lead the Social Computing area. He holds a PhD (cum laude), a MSc (cum laude) and a BSc in Computer Science and Telematics from Graz University of Technology (Austria). He is a former FFG, Marshall Plan and ERCIM fellow and has 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 has been visiting Yahoo! Labs Barcelona in 2014 and CWI Amsterdam in 2015 (two times). Christoph's research interests include AI, Machine Learning, Recommender Systems and the Science of the Web. He was involved, either as a collaborator or a project leader, in various national and international EU-funded research projects that dealt with social technologies and recommender systems. Currently, he is driving a research project that tries to understand, predict and change online food preferences to tackle health-related food issues such as diabetes or obese. Since 2010, he published two books and over 60 scientific articles in top venues and journals, e.g., Wiley JASIST, ACM TiiS, Elsevier ComCom, WWW, ACM WebSci, ACM CIKM, ACM CSCW, ACM RecSys, ACM IUI, ACM HT and ACM UMAP. He is also the winner of several Best Paper/Poster Awards and Nominations. He regularly acts as a PC member on several top-tier conferences and co-organizes or co-chaires a number of workshops and conferences. Recent examples include WWW'16, ACM UMAP'16, ACM HT'16 or ACM IUI'16.
