Ridha is an Associate Professor in the Department of Mechanical Engineering, Faculty of Engineering at the University of Malaya. He obtained Doctor of Engineering from Utsunomiya University Japan in 2015, specializing in magnetic abrasive finishing for superfinishing of tube internal surface for clean environment applications. Prior to his doctoral study, he worked in Mazak Corporation as a Senior Mechanical Design Engineer focusing on CNC prototype machine design and evaluations for mass production and customizations. He involved in the design and development of several CNC machines including Mazak's Quick Turn Nexus series and had performed more than 100 variations of cutting parameters to confirm the machine`s limits and capabilities. Currently, he is collaborating with the Joining and Welding Research Institute (JWRI), Osaka University Japan to develop friction stir welding process in a sustainable way. The project explores the possibilities of joining similar and dissimilar materials such as polycarbonate/aluminium, aluminium/stainless steel, magnesium/steel, aluminium/copper for various fundamental and applications in automotive and semiconductor industries. He was awarded the Distinguished International Associate from the Royal Academic of Engineering UK in 2023 for his project on friction stir welding. He actively applies for research grants and up to date, he has secured more than 30 projects from domestic and international funders. He has completed supervision of 7 PhD and 8 Master students, and currently supervising 7 PhD and 1 Master candidates.

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.

P. Raveendran received the B.Sc and M.Sc degrees in electrical engineering from South Dakota State University, Brookings, South Dakota, USA in 1984 and 1985 respectively. He was a systems designer with Daktronics, U.S.A before joining the Department of Electrical Engineering at University of Malaya, Kuala Lumpur, as a lecturer in 1986. In 1992, he received a Ronpaku scholarship from Japan to pursue Doctorate in Engineering, which he completed in 1994 at University of Tokushima, Japan. He was promoted to Associate Professor in 1995 and was promoted to Professor in 2003. His research areas include image and video analysis, formulation of new image descriptors for image analysis, fast computation of orthogonal moments, analysis of EEG signals, and data modeling of substance concentration acquired from non-invasive methods. His contributions can be seen in the form of journal publications, conference proceedings, chapters in books and an international patent to predict blood glucose levels using non-parametric model. He has successfully supervised to completion 17 Ph.D students and 13 students in M.Eng.Sc (Masters by research). He is currently a Senior IEEE member and also a member of the Signal Processing Society.
