Sebastian Skritek

Sebastian Skritek is a Senior Lecturer at the Technische Universität Wien in the Department of Databases and Artificial Intelligence. His research primarily focuses on database theory, semantic web technologies, and query processing.

Research interests include foundational aspects of database systems, complexity analysis of query languages, and optimization techniques for semantic web applications. His work bridges theoretical computer science with practical database implementations.

His publications demonstrate a consistent focus on query evaluation complexity and optimization, particularly in SPARQL and conjunctive query systems. Recent work explores diversity in query answers and tractability boundaries.

Supervision includes guiding students in database theory projects and theses. Research projects include 'SEE: SPARQL Evaluation and Extensions' and 'Theoretical Tractability vs. Practical Computation'.
