Manuel Rigger is an Assistant Professor leading the TEST Lab, which is part of the PL/SE group at the School of Computing, National University of Singapore. He is working on software reliability, data-centric systems, and programming language implementation. In his recent work, he has been focusing on automatically testing Database Management Systems, part of which he found over 450 bugs in widely-used systems such as SQLite, MySQL, PostgreSQL, MariaDB, and CockroachDB. Prior to joining NUS, Manuel was a postdoc at the Advanced Software Technologies Lab at ETH Zurich, mentored by Zhendong Su. He completed his PhD at Johannes Kepler University Linz, mentored by Hanspeter Mössenböck, where he worked on the safe and efficient execution of unsafe languages (project Sulong). Part of his work was integrated into Oracle’s GraalVM to support the execution of LLVM IR on this platform.
