Prof. Dr. Matthias Renz (Dr. rer. nat., habil)
Dr. Renz is Professor at the Department of Computer Science at the Christian-Albrechts-Universität zu Kiel (CAU, University of Kiel). Before he joined CAU in Summer 2018, Dr. Renz was Associate Professor in the Computational and Data Science Department at the George Mason University (GMU), Fairfax, VA, USA. He received his Ph.D. in Computer Science at the Ludwig-Maximilians University (LMU) Munich 2006, where he served as lecturer after finishing his habilitation (venia legendi) 2011. Before Dr. Renz moved to GMU 2016, he was acting chair of the database systems group at the LMU. Dr. Renz was co-founder and co-director of the Data Science Lab at LMU Munich which has been founded in cooperation with Siemens AG. Dr. Renz also co-founded and co-directed the Mason’s DataLab at the College of Science at the George Mason University, where he headed the DataLab's DataScience division.
Dr. Renz’s main research interest is Data Science with focus on scalable methods for searching and mining in very large, heterogeneous, dynamic and potentially uncertain data. He has published more than 120 papers on peer-reviewed international conferences and in international journals. His work has received considerable attention by the corresponding community with more than 2500 citations achieving an H-index of 23 and an i10-index of 51. He gave several invited tutorials, seminars, and keynotes on international conferences and in 2016, his work received the 10-Year Best Paper Award at the International Conference on Database Systems for Advanced Applications. His work has been supported by governmental research grants and industrial funding including Siemens AG, Volkswagen Group, Audi AG, and BMW AG. He has been a program committee member for several international conferences and workshops, including SIGMOD, VLDB, ICDE, and KDD. Furthermore, Dr. Renz co-organized and chaired several international conferences and workshops, including SSTD, ACM SIGSPATIAL, DASFAA, ACM SIGSPATIAL QUeST, ACM SIGMOD GeoRich, and ACM SIGSPATIAL LocalRec.
Areas and Statement
My research interests mainly address Data Science, Data Mining and Management and Knowledge Discovery with a focus on scalable methods for searching and mining in very large, heterogeneous, dynamic and potentially uncertain data=, as well as Spatial and Spatiotemporal Databases.
In my early studies, I have addressed spatial databases and shifted later toward spatiotemporal databases with a concentration on moving object management and query processing in traffic network data. One of my main research interest has been on managing and mining uncertain data with a focus on probabilistic query processing and mining in spatial and spatiotemporal data.
My current research activities are going toward data science and are highly interdisciplinary addressing areas such as Engineering, Medicine (Health-Analytics), Transportation (Smart Transportation), Urban Analytics, and areas of political, legal, and social sciences. In addition to my continuing work on concepts for management and analysis of user-generated spatial and spatiotemporal data and data with spatial context information, I have recently started studies on Heterogeneous Information network (HIN) analysis. For example, in an interdisciplinary collaboration with the team from the Schar School of Policy and Government, we study methods for identifying patterns of interaction of key players in the finance and government sector.

DataLab is an initiative of the College of Science at George Mason University conducting multidisciplinary research and developing solutions on large-scale Data Analytics. Our faculty also provides education and training in Data Science and Data Analytics.
DataLab engages researchers across George Mason working on Computational and Data Sciences, as well on data-intensive application areas, such as Medical and Life Sciences, Computational Social Sciences, Earth Systems, GeoIntelligence and Transportation, and Evidence-based Policy.
We aim to partner with Academia, Industry, and Government in a collaborative, diverse, cross-disciplinary environment, to seek and try new ideas for innovation, education, and best practices.
