DR EMILE HORAK (Pr Eng, FSAICE) obtained his first to highest engineering qualifications from the University of Pretoria. He also studied at the Universities of California, Berkeley and UNISA. His career started in technology transfer and research implementation at the CSIR, which remained his passion throughout his career as a pavement engineer. He had a short stint with a major contractor developing toll concessions and design-build-operate opportunities. He established himself as specialist consultant, and as such contributed to a number of mediation and arbitration cases on roads, materials and airports. He spent ten years as Professor and Head of the Department of Civil Engineering, University of Pretoria. His researcher status is recognised nationally and internationally, and he has more than 300 papers, journal articles and peer-reviewed conference papers to his credit.

ANDREW EARL is currently pursuing a double Master’s (Ma and MSc) in Innovation Design Engineering between the Royal College of Art and Imperial College London. Prior to undertaking his Master’s, he graduated (BSc (Hons)) from the University of Cape Town Civil Engineering Department in 2016. He maintains a keen interest in urban issues, particularly those around transport in the South African context. During his time in the United Kingdom he is learning new approaches to problem solving in a variety of contexts and aims to bring this knowledge home after graduating.
ANDREW EARL目前正在英国皇家艺术学院和伦敦帝国理工学院攻读创新设计工程双硕士(硕士和硕士)学位。在攻读硕士学位之前，他于2016年毕业于开普敦大学土木工程系(荣誉理学士)。他对城市问题，特别是南非的交通问题保持着浓厚的兴趣。在英国期间，他正在学习在各种情况下解决问题的新方法，并计划在毕业后将这些知识带回家。
