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 level - 30 million as the PI. Examples of outlets where my work has been published includes NATURE Sustainability, JASIST, EPJ Data Science, UMUAI, WWW, AAAI 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 prestigious 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.
