Niels Pinkwart has a background in Computer Science and Mathematics. He received his PhD from the University of Duisburg-Essen in 2005 with a dissertation on collaborative educational modeling systems. After a post-doctoral position at the Human-Computer Interaction Institute of Carnegie Mellon University, he accepted offers for Assistant Professor and Associate Professor positions at Clausthal University of Technology. In 2013, he moved to the Humboldt-Universität zu Berlin where he since heads the research group "Computer Science Education / Computer Science and Society", the ProMINT Kolleg and the Center of Technology Enhanced Learning located in the Professional School of Education of HU Berlin. In addition to his activities at HU Berlin, Prof. Pinkwart acts as Principal Investigator at the Einstein Center Digital Future and at the Weizenbaum Institute for the networked society (German Internet Institute), and holds a scientific director position at DFKI (German Research Center for Artificial Intelligence) since 2019. Within the German Computer Science Association, Prof. Pinkwart is currently co-chair of the working group on Learning Analytics and member of the steering committee of the section on Educational Technologies.
Sannyuya Liu has been a professor and the executive deputy director in National Engineering Research Center for E-learning (NERCEL), Central China Normal University (CCNU) since 2006. He received the Ph.D. degree in systems engineering from Huazhong University of Science and Technology (HUST), Wuhan, China, in 2003. His research interests include educational data mining, AI in education, ICT in education, educational technology, etc. To date, he has published more than 100 peer-reviewed articles, 7 books, and more than 30 national invention patents. He has also led many National Key R&D Projects of China on Personalized Learning and Intelligent Tutoring Technologies, e.g. he has been funded by National Natural Science Foundation of China on Group Behavior-Emotion-Cognition Modeling in Online Learning. He successfully led NERCEL R&D team in developing starC, a SPOC learning platform based dual-track teaching philosophy for supporting Informatization reform and teaching innovation in higher education. He was awarded with one First and one Secondary Prizes for Scientific and Technological Progress of Hubei Province respectively. Particularly, he proposed a systematic framework of Quantified Learning in a book named “Quantified Learning: Data-Driven Learning Behavior Analysis” published by Science Press of China, which has a significant impact on making the data-driven human learning mechanism research more accessible and promoting more applications of big data in education.
