Arosha is a Lecturer in Civil Engineering Materials at the School of Physics, Engineering and Computer Science at the University of Hertfordshire.

Previously he held the position of Research Associate & Managing Editor at the University of Sheffield (2022-2023) where he worked mainly for the editorial management of a leading international journal of Materials and Structures along with the Editor-in-Chief, Prof. John Provis. In this previous role, he also performed research work on innovative cements for applications in the nuclear sector and construction, mainly looking into magnesia-based cements.

Arosha completed his PhD in Civil Engineering at the University of Queensland in Australia. His PhD mainly focussed on assessing various early age properties of high-performance concrete mixes. His PhD thesis was awarded the Dean’s award for Outstanding Higher Degree by Research Theses 2022 by independent examiners for making a substantial contribution to the field of research of concrete technology.
