Currently leading technical innovation at Future-tech, Mark is at the forefront of sustainable IT operations, focusing on how data infrastructure can meet increasing digital demand while reducing environmental impact.

He is also the creator of TheVentGuide, a global reference for data centre industry events, and a frequent contributor to standards development and best practice frameworks.

Dawn is the CEO of Pure Data Centres Group building and operating hyperscale data centres. Before joining Pure she led a multi-billion transformation programme for National Grid across both the gas and electricity transmission businesses. This followed several senior engineering appointments as: the Group Engineering Director for Merlin Entertainments with responsibility for engineering delivery and standards across the worldwide portfolio of theme parks; and the Head of Engineering at Gatwick Airport. She joined Gatwick after 23 years as an Engineering Officer in the Royal Air Force.

She is a Trustee of the Royal Academy of Engineering and Chairs the Audit & Risk Committee and a Trustee of the Air League. She was the longest serving President of the Women’s Engineering Society, turning it around over a 5 year tenure, and is currently the Chair of the iMasons People Committee.

She was honoured with a Fellowship of the Royal Academy of Engineering in October 2020 in recognition of her outstanding contribution to the engineering profession and was appointed a Dame Commander of the British Empire (DBE) for services to engineering in the King’s New Years Honours 2023.

Dr. Jon Summers is Scientific Lead in Data Centres at Research Institutes of Sweden (RISE), an Adjunct Professor in Fluid Mechanics at Lulea Technical University in Sweden, a Visiting Professor in Thermofluids at the University of Leeds and chair of the Future Technologies Symposium of the Open Compute Project. During the last 25 years, he has worked on many government and industry funded projects requiring the use of computation. Having built and managed compute clusters to support many research projects, Jon chaired the High-Performance Computing User Group for 20 years at the University of Leeds. In the last eight years Jon’s research has focused on a range of thermal and energy management projects within Data Centres, Heating Ventilation and Air Conditioning and industrial sectors. Since early 2013 Jon has been involved in liquid cooled IT research projects, focussing both at the data centre and the microprocessor scales, which has been further transformed by the opportunities of integrated digital infrastructure research at the RISE ICE test and demo datacenter facility, which includes large testbeds supporting industry and academia. His research and technological development at RISE during this decade is focussed on making the digital infrastructure as energy efficient and sustainable as possible
