Torsten Hoefler is a Professor of Computer Science at ETH Zurich, a member of Academia Europaea, and a Fellow of the ACM and IEEE.  Following a “Performance as a Science” vision, he combines mathematical models of architectures and applications to design optimized computing systems.  Before joining ETH Zurich, he led the performance modeling and simulation efforts for the first sustained Petascale supercomputer, Blue Waters, at the University of Illinois at Urbana-Champaign.  He is also a key contributor to the Message Passing Interface (MPI) standard where he chaired the "Collective Operations and Topologies" working group.  He has made fundamental contributions to large-scale parallel learning systems. 

For his work, Torsten received the IEEE CS Sidney Fernbach Memorial Award, the ACM Gordon Bell Prize in 2019, the ISC Jack Dongarra award, the IEEE TCSC Award of Excellence (MCR), ETH Zurich's Latsis Prize, the SIAM SIAG/Supercomputing Junior Scientist Prize, the IEEE TCSC Young Achievers in Scalable Computing Award, and the BenchCouncil Rising Star Award.  Following his Ph.D., he received the 2014 Young Alumni Award and the 2022 Distinguished Alumni Award of his alma mater, Indiana University.  His MSc thesis won the best student award of TU Chemnitz in Germany.  Torsten was elected to the first steering committee of ACM's SIGHPC in 2013 and he was re-elected for every term since then.  He was the first European to receive many of those honors; he also received both an ERC Starting and Consolidator grant.  His research interests revolve around the central topic of performance-centric system design and include scalable networks, parallel programming techniques, and performance modeling for large-scale simulations and artificial intelligence systems.

Torsten published more than 300 peer-reviewed scientific conference and journal articles and authored chapters of the MPI-2.2 and MPI-3.0 standards.  Torsten won best paper awards at the ACM/IEEE Supercomputing Conference 2010 (SC10), EuroMPI 2013, SC13, SC14, SC19, SC22, SC23, SC24, IPDPS'15, ACM HPDC'15 and HPDC'16, ACM OOPSLA'16, and other conferences.  According to Google Scholar, his work has been cited more than 17,000 times and his h-index is 70.  He was invited to present keynotes at significant conferences and workshops such as ACM's Federated Computing Research Conference (FCRC), ICPP'23, DISC'20, Supercomputing Asia, HPC China, HPC Asia, MLHPC, PPAM, PARCO, EuroMPI, and many others.
