Basil Ell studied Computer Science (B.Sc., M.Sc.) at Mannheim University of Applied Sciences, Pohang University of Science and Technology (South Korea) and Indian Institute of Technology (IIT) Madras (India). In 2009 he joined the Knowledge Management group at the Institute of Applied Informatics and Formal Description Methods (AIFB) at Karlsruhe Institute of Technology (KIT), where he obtained a Ph.D with the thesis "User Interfaces to the Web of Data based on Natural Language Generation" in 2015 under the supervision of Professor Rudi Studer. There he was mainly working on Natural Language Generation from SPARQL queries and RDF graphs and on semantically-enhanced Virtual Research Environments for the History of Education. He joined the Semantic Computing group at the Cluster of Excellence Cognitive Interaction Technologies (CITEC) in Bielefeld/Germany in May 2016 as a postdoctoral researcher. In addition to the position in Bielefeld he joined SIRIUS labs in Oslo/Norway in September 2018 - thus cummuting between Bielefeld and Oslo. He is currently interested in the Semantic Web and Natural Language Processing in general and in particular in knowledge base population, semantic parsing, information extraction from text (relation extraction), information extraction from tables (table understanding), property lexicalization, natural language generation from RDF data, and frequent pattern mining from RDF graphs.
