Dr John (Temitope) Kolawole

BSc (First Class Honours) MSc PhD

  • EPSRC Doctoral Prize Fellow
  • Research Associate in 3D Concrete Printing

Research and expertise

My research themes – low-carbon construction materials, valorising wastes into concrete matrices, self-sensing and self-healing materials, durability and early-age cracking in cement composites, rheology of binder systems, and additive manufacturing with concrete

After completing my BSc, my 12+ years career has been in research, development, and practice, accumulating fellowships and awards worth over £250K. In my current role, I am a materials and rheology specialist undertaking research and teaching, contributing to the world’s pioneering and UK-leading consortium advancing 3D concrete printing (3DCP) technology. However, the impact of my expertise is beyond 3DCP, I am currently active in the above six research themes strategically aligned with Sustainable, Resilient and Smart Infrastructure, with 40+ publications outcomes in top journals, working with international collaborators, developing innovative test methods for concrete applications, and establishing some advanced concrete science. I also consult for companies working with concrete, creating impact in enterprise and knowledge transfer.

I have worked on UK funded multimillion projects with multidisciplinary collaboration, organising across the group; successfully supervised/mentored several research students, supported international visiting researchers and participated in organising international conferences and workshops. I am actively involved in professional bodies, such as RILEM, and their technical committees developing research/industry standards on construction and concrete materials. I completed my TWAS-funded PhD investigating the roles of rheology in the plastic settlement/shrinkage cracking of early-age concrete, advancing the fundamental understanding of concrete behaviour, with four prominent awards, 6 top journal papers, 1 conference paper, and several international presentations.

Profile

My 12+ years career has mainly been in academia (research, teaching & service): research fellow (3 years), doctoral researcher & teaching assistant (3 years), lecturer (3 years), research masters candidate (2 years); and briefly in the industry as a graduate engineer (2 years).

I graduated with a First Class Honours BSc in Building in 2010 and MSc in Building Structures in 2015 at Obafemi Awolowo University (OAU), Ile-Ife, Nigeria. I completed my PhD in early 2020 and became a Consolidoc Postdoctorate Fellow briefly at Stellenbosch University, South Africa, before joining Loughborough University in July 2020 as a Postdoctoral Research Associate. Before my PhD, I was a lecturer at OAU, positively impacting the next generation of graduates for academic excellence.

In December 2022, I was awarded the prestigious EPSRC Doctoral Prize Fellowship at Loughborough University for independent research to explore innovative solutions for overcoming the inherent lagging performance of 3D-printed concrete. Shortly afterwards, I became a Fellow of C-DICE, UK’s largest investment in postdoctoral development.
