Christoph Koch is a professor of Computer Science at EPFL, specializing in data management. Until 2010, he was an Associate Professor in the Department of Computer Science at Cornell University. Previously to this, from 2005 to 2007, he was an Associate Professor of Computer Science at Saarland University. Earlier, he obtained his PhD in Artificial Intelligence from TU Vienna and CERN (2001), was a postdoctoral researcher at TU Vienna and the University of Edinburgh (2001-2003), and an assistant professor at TU Vienna (2003-2005). He obtained his Habilitation degree in 2004.

He has won Best Paper Awards at PODS 2002, ICALP 2005, SIGMOD 2011, VLDB 2014, and GPCE 2017, an Outrageous Ideas and Vision Paper Award at CIDR 2013, a Google Research Award (in 2009), and an ERC Grant (in 2011). He (co-)chaired the program committees of DBPL 2005, WebDB 2008, ICDE 2011, VLDB 2013, and PODS 2019, and was PC vice-chair of ICDE 2008 and ICDE 2009. He has served on the editorial board of ACM Transactions on Internet Technology and as Editor-in-Chief of PVLDB.


Current research projects

Past research projects

  • MayBMS: a probabilistic database management system (released on sourceforge)

  • data management in video games and simulations

  • In the past, I have worked on numerous other projects related to semistructured data, data stream processing, answer set programming, data integration, database theory (particularly expressiveness and complexity of query languages), and others. The project pages have ceased to exist, but you can generally read about these projects in my list of publications.
