Tobias Grosser is an Associate Professor at the University of Cambridge and an advocate for open-source-first research. Tobias co-founded the Polyhedral loop optimization framework Polly, the FPL Presburger Library in MLIR, introduced with LLHD/CIRCT hardware-design into the LLVM community, and is regularly teaching MLIR-style compiler design using the Python-Native xDSL compiler project designed to lower the barrier of entry into the LLVM ecosystem. Tobias worked at ENS Paris, ETH Zurich, the University of Edinburgh, and now the University of Cambridge and supervises several PhD students who actively contribute the the open-source compiler ecosystem.
