Scientific Leader in Data Centers, 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. During the last 25 years, I have worked on a number of government and industry funded projects requiring the use of computation. Having built and managed compute clusters to support many research projects, I chaired the High Performance Computing User Group for 20 years at the University of Leeds. In the last eight years my research has focused on a range of thermal management and energy flow projects within the Data Centre, Heating Ventilation and Air Conditioning and industrial sectors. Since early 2013 1 have been involved in liquid cooled IT research projects, focusing both at the data centre and the microprocessor scales, which has been further transformed by the opportunities of integrated digital infrastructure research at RISE. My current research focuses on thermal and energy management of microelectronic systems, which has led to my many invited talks around the globe within the data centre community.
