Prof. Dr. Michael Grossniklaus


Michael Grossniklaus is a professor of Computer Science at the University of Konstanz. Since October 2022, he has been part of the Directorate of the Centre for Human | Data | Society. He studied computer science with a focus on databases and information systems at ETH Zürich and graduated with a diploma thesis in context-aware content management in 2001. In 2007, he received a doctorate (thesis: An Object-Oriented Version Model for Context-Aware Content Management). Since 2013 he has been chairing his research group at the University of Konstanz, first as a junior professor and since 2017 as a full professor. He is one of 25 founding Principal Investigators of the Cluster of Excellence “Centre for the Advanced Study of Collective Behaviour”. Since 2022 he has been the Scientific Co-Lead of the Advanced Data and Information Literacy Track, which aims to increase and enhance data and information literacy for students of all disciplines at the University of Konstanz. Michael has expert knowledge in Database Systems, Query Optimization, Graph Databases and Data Streams. He aims to develop innovative database technologies to support novel and emerging application domains. His current research is focused on the design and development of algebraic optimisation techniques for graph databases and data stream processing in the area of event detection techniques.
