Dr Jon Summers is the scientific lead in data centres at RISE Research Institutes of Sweden, Adjunct Professor in Fluid Mechanics at Lulea Technical University in Sweden, and a Visiting Professor to the Institute of Thermofluids at the University of Leeds in the UK. He has worked on government and industry funded projects using high performance computing (HPC). Having built and managed compute intense clusters to support research projects, he chaired the HPC User Group for 20 years at the University of Leeds. Recently Jon’s research has focused on a range of thermal management and energy flow projects within the Data Centre, HVAC, and industrial sectors. Since 2011 he has been involved in liquid cooled IT research projects, focusing both at the data centre and the microprocessor scales, which has been further transformed by opportunities of integrated digital infrastructure research at RISE, including the operation of large-scale testbeds. Focusing on thermal and energy management has led to Jon being invited to present and sit on panels within the data centre community. Jon also has an interest in the physical limits of computation.
