 Profile

Georg studied theoretical physics and philosophy at the University of Heidelberg and obtained a PhD in computer science from the Max Planck Institute for Informatics in Saarbrücken. After a series of positions at German universities he joined the University of Sheffield in 2005.
 Research interests

Georg works mainly on logical and algebraic methods in computer science, formalised mathematics with interactive theorem provers and program verification and correctness.
His interests range from foundational work on the axiomatisation and semantics of sequential and concurrent computing systems to applications in the design and implementation of program verification software.
