Career Bio:

Dr. Md. Rajibul Islam is a distinguished researcher and academic with a strong interdisciplinary background in computer applications and photonics engineering. He earned his Bachelor of Computer Applications (BCA) from Indira Gandhi National Open University, New Delhi, India, in 2004, followed by a Master of Science in Information Technology (Biometric Image Processing) from Multimedia University, Malaysia, in 2010.
Dr. Islam began his professional journey as a Research Assistant and Software Engineer at various university research institutes and R&D divisions within Malaysian software firms. In 2014, he returned to academia to pursue a Ph.D. in Physics (Photonics Engineering) at the Photonics Research Centre, University of Malaya, which he completed in 2017.
He recently concluded a prestigious two-year research fellowship at the Photonics Research Institute of the Hong Kong Polytechnic University in August 2025. Upon completion, he resumed his academic duties at the Bangladesh University of Business and Technology (BUBT), where he currently serves as Chairman of the Department of Data Science and Engineering, a role he assumed on January 1, 2026. Prior to this, he held the position of Associate Professor in the Department of Computer Science and Engineering at BUBT.
Earlier in his academic career, Dr. Islam also served as an Assistant Professor and Head of the Department of Computer Science and Engineering at the University of Asia Pacific (UAP). He was a Visiting Ph.D. Researcher at the University of Limerick, Ireland, through the Erasmus Mundus – INTACT scholarship program.
Dr. Islam's research interests span machine learning, artificial intelligence, data mining, optical fiber sensors, and photonic devices. With approximately 100 peer-reviewed scientific publications, along with several books and book chapters, he is a highly active contributor to the global scientific community. He also serves as a reviewer for numerous international journals and participates regularly in the scientific committees of international conferences.
