Professor Dr. Azhar Ariffin earned his Bachelor of Science in Chemistry with honors from Universiti Malaya in 1993, followed by a Ph.D. in Asymmetric Organic Synthesis from the University of Nottingham, UK, in 1999. Upon completing his studies, he returned to Malaysia and began his career as a young lecturer in the Chemistry Department at the University of Malaya. Over the years, he climbed the academic ranks, achieving the status of Associate Professor in 2003 and attaining the position of full Professor in 2016. From 2021 to 2022, Professor Dr. Azhar Ariffin served as the Head of the Chemistry Department before assuming the role of Deputy Dean of Research at the Faculty of Science from 2022 to 2024. Currently, he holds the position of Deputy Dean of Development at the Faculty of Science. His research endeavors predominantly focus on organic synthesis, with a specific interest in developing bioactive compounds, including derivatives of butylated hydroxytoluene (BHT), oxadiazole, thiadiazole, and triazole for use as antioxidants. Additionally, he explores the synthesis of various derivatives of quinazoline for potential applications in anticancer treatments. Currently, his research involves the creation of carbazole derivatives for their utility in organic light-emitting diode (OLED) materials, with a focus on improving the C(sp²)-N bond formation through the Buchwald-Hartwig reaction under microwave irradiation. Professor Dr. Azhar Ariffin's contributions extend beyond his home institution, as he served as an Experienced Researcher at Kaunas University of Technology from 2019 to 2023 under the MEGA HORIZON 2020 PROJECT: MARIE SKŁODOWSKA-CURIE RESEARCH AND INNOVATION STAFF EXCHANGE.

I have been working as a senior lecturer in the Department of Mechanical Engineering at the University of Malaya, Malaysia. I am pioneering research in energy, environment, supply chain modelling, and metallurgy, with a focus on optimisation, techno-economic analysis, and lifecycle assessment. I also teach key courses in mechanical engineering, such as fluid mechanics, heat & mass transfer, and thermodynamics, while developing research grants and establishing collaborative partnerships.Previously, I worked as a Research Fellow at the National University of Singapore (NUS) and conducted research in the area of low-carbon technologies, particularly on hydrogen energy vectors. Before joining NUS, I completed my role as a Research Fellow at HILT-CRC and Victorian Hydrogen Hub (VH2) projects at Swinburne University of Technology, Australia. Before joining Swinburne, I worked for the Hydrogen Energy Supply Chain (HESC) project at Federation University, Australia, and the Waste to Energy and Resource Recovery project at the UNSW, Sydney. I received my PhD in Chemical Engineering from Monash University with the prestigious Postgraduate Publication Award (PPA). I obtained my MPhil and bachelor’s degree in mechanical engineering from the University of Adelaide and DUET Bangladesh.I have been consistently listed among the world's top 2.0% of scientists in the subfield of energy, published by Elsevier and Stanford University since 2021. I am a certified chemical, mechanical, and material engineer from the world's top professional bodies with extensive research experience in process modelling (Aspen Plus, HYSYS, and HSC Chemistry), hydrogen energy, gasification, solar energy, green iron and steel, biofuel, CFD, technoeconomics, and LCA. I have published over 60 research articles, receiving over 4700 citations with an h-index of 28 (Google Scholar). Throughout my career, I have supervised dozens of research students at the undergraduate and postgraduate levels. Besides, I have a decade of teaching experience at the University of Malaya, Monash University, Victoria University, and BCMC College.Please reach out me for research collaboration and PhD positions at shahabuddin@um.edu.my. Thank you!
