Andrew is the Innovation Advisor at Field Ready and part of its core team. Field Ready uses disruptive technologies (such as digital fabrication) to transform disaster relief supply chains. The idea is to make sure that aid workers can always have the supplies they need to do aid work.

Andrew also works a consultant for the World Bank on Open Data (preparing an online course and supporting local government open data in Tanzania). Recent previous work included for the 'Global Dimension in Engineering Education' project in Europe (on supporting academics) and for the global engineering body the World Federation of Engineering Organisations (on initiatives such as engineering capacity building in Africa).

He was the first staff Chief Executive of Engineers Without Borders UK until summer 2013 where he made significant progress in the organisation's scope and effectiveness, including a much stronger focus on engineering education and developing its 'massive small change' philosophy.

He is a trustee of disaster relief training organisation RedR UK, where he previously worked on external relations in the UK and as Interim Country Director in Kenya. He is a director of the Appropedia Foundation which runs the www.appropedia.org website - a sustainability wiki. Andrew is a co-founder and is on the board of the Centre for Global Equality (formerly the Humanitarian Centre) in Cambridge, which convenes partnerships to tackle the root causes of poverty. He was the technical editor of the world's first global report on engineering, the UNESCO Engineering Report, which focused on opportunities and challenges for development. Among Andrew’s current interests is the use of Lego to promote generational change in sub-Saharan Africa, and developing the ‘massive small change’ concept for wider use across society.
