Bertram Ludäscher is a leading figure in data and knowledge management, focusing on the modeling, design, and optimization of scientific workflows, provenance, data integration, and knowledge representation. He is one of the founders of the open source Kepler scientific workflow system project and a co-lead of the DataONE Working Group on Provenance in Scientific Workflows. Ludäscher also develops workflow technology for quality control and data curation; e.g., of biodiversity data in natural history collections. He leads the NSF-funded Euler project, where he is developing logic-based methods for the alignment and merging of biological taxonomies.

In addition to his appointment as a professor at the iSchool, Ludäscher holds an appointment at the National Center for Supercomputing Applications (NCSA) and an affiliate appointment at the Department of Computer Science. Before coming to Illinois in Fall 2014, Ludäscher was a professor at the Department of Computer Science and the Genome Center at the University of California, Davis. He previously worked at the San Diego Supercomputer Center at UC San Diego where until 2004 he was an associate research scientist, leading the Knowledge-Based Information Systems Lab. He received his MS in computer science from the Technical University of Karlsruhe in 1992 and his PhD in computer science from the University of Freiburg in 1998.
