New members from business, academia and the charity have been appointed to the board of business, academia and the charity.
The new members will oversee the department's ambition to bring the power of science and technology to bear to overhaul public services, tackle challenges posed by digital exclusion and fuel economic growth.
The appointments include: Adam Tickell, vice-chancellor of the University of Birmingham; Nicola Hodson, chief executive of IBM UK and Ireland, and former board member at the UK Council for Child Internet Safety; Helen Milner OBE, group chief executive of the Good Things Foundation; and Paul Willmott: chair of the Central Digital & Data Office and Chief Digital Advisor at KIRKBI (LEGO Holding).
The board will provide over-arching strategic guidance and scrutiny, as the department looks to maximise the potential of digital, data and technology to deliver for the British public.
Dominic Field, Liz Cohen and Jason Chin will continue their roles on the departmental board, with Dominic Field assuming the role of lead non-executive director (NED).
Technology secretary Peter Kyle said: "As we transform DSIT to unleash the power of technology to improve lives for people across the country, working in lockstep with business, academics and charities will be essential.
"Bringing Adam, Nicola, Helen and Paul on to the board brings in some of Britain’s brightest and most passionate minds to help us drive these ambitions forward, so we can put technology to work for people nationwide.
Department Lead NED Dominic Field said: "I am excited that we have assembled such an exceptionally talented group of NEDs who will bring deep and relevant experience. I look forward to working with them to support the civil service and ministerial team in delivering DSIT’s key priorities for the nations."
