His research interests mainly involve synthesis and applications of advanced materials, characterization, reaction engineering studies as well as preliminary process design, with particular focus on CO2 capture technologies and intensified reforming processes for hydrogen production. The results of his work have significantly advanced research in the area of process intensification and have made a notable impact in the field, proving the progress beyond the state-of-the art. He was awarded the EFCE Excellence Award in Process Intensification in 2019 for his PhD thesis entitled "Intensification of sorption enhanced steam methane reforming for high-purity hydrogen production"
