Prof. Mario A. Nascimento from University of Alberta, Canada and Dr. Theodoros Chondrogiannis from University of Konstanz, Germany will visit the Data Management group on February 13, 2019.
Mario A. Nascimento is a Full Professor at (and since July 2014 serves as Chair of) the University of Alberta's Department of Computing Science. He earned his PhD in 1996, and before joining the University of Alberta in 1999, he was a researcher with the Brazilian Agency for Agricultural Research and also an adjunct faculty member with the Institute of Computing of the University of Campinas. In addition, Mario has been a visiting professor at the National University of Singapore's School of Computing (Fall/2005), Aalborg University's Department of Computer Science (Winter/2006), LMU Munich (Fall/2013-Winter/2014) and also had an appointment as Visiting Professor at the Federal University of Ceara in Brazil (2013 and 2014). According to Google Scholar (as of July/2015) his publications have been cited 2,750+ times, earning him an H-index of 27. His main research interests lie in the areas of Spatio-Temporal Data Management and Data Management for Wireless Sensor Networks. Besides often serving as a program committee member for the main database conferences, and as (co-) chair of several workshops and symposia, Mario has also served as ACM SIGMOD's Information Director (2002-2005) and ACM SIGMOD Record's Editor-In-Chief (2005-2007). He is currently a member of the VLDB Journal's Editorial Board, the SSTD Endowment's Board of Directors, and has been a senior member of the ACM since 2007. Finally, he finds it amusing writing about himself in the third person.
Theodoros Chondrogiannis is a Post-doctoral research at the University of Konstanz, Germany. He studied computer science in his home country of Greece. He obtained his 4-year BSc degree in Computer Science and Technology with a focus on Software Systems from the Department of Computer Science and Technology of the University of Peloponnese in 2009, and his MSc degree in Advanced Information Systems from Department of Informatics and Telecommunications of the National Kapodistrian University of Athens in 2013.
In 2013, Theodoros was awarded a PhD fellowship from the Free University of Bozen-Bolzano and he started his PhD at the Faculty of Computer Science. In 2017, he completed successfully his PhD studies and received a doctorate for his thesis entitled Efficient Algorithms for Route Planning Problems on Road Networks. After his doctorate, he continued working as a postdoctolar researcher at the Faculty of Computer Science until December 2017, when he joined the University of Konstanz.
Prof. Dr. Matthias Renz from Christian-Albrechts-Universität zu Kiel, Germany will visit the Data Management group on February 1, 2019.
Dr. Renz is a Professor at the Department of Computer Science at 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 George Mason University (GMU), Fairfax, VA, USA. He received his Ph.D. in Computer Science at Ludwig-Maximilians-Universität München in 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 Munich. 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 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.
The 16th International Symposium on Spatial and Temporal Databases (SSTD 2019) will be held in Vienna, Austria; Prof. Bouros is the general co-chair.
