Tobias Kohn studies optimisations in Python, particularly in the context of scientific applications. He investigates the possibilities for, and limitations of, performance improvements of both Python as a language, as well as its current implementations. The focus of his research is on static analysis, program transformations and virtual machines.  Additionally, he also works in the field of computer science education and is an active member of ACM's special interest group SIGCSE.

Biography

Tobias Kohn received his MSc in Mathematics from ETH Zurich und has taught at Swiss grammar/high schools for several years before obtaining a PhD in Computer Science, also from ETH Zurich.  He subsequently joined a machine learning group at the University of Oxford and is now a member of the Computer Architecture group at the University of Cambridge.  Since March 2020 he is also a Research Fellow at Hughes Hall College.
