Background

Background

Zelong is a Geotechnical researcher with experience in Large-scale infrastructure monitoring. He is currently working as a research associate on the EPSRC funded project ACHILLES to assess, monitor, design and repair the performance of the ground. Prior to involvement in the ACHILLES, he completed a PhD in Strategies for improving railway track-bed settlement. During his PhD, he also involved with industry consultancies with Tensar, Tarmac and Network Rail.
