Md. Saddam Hossain is a Scientific Officer at the National Institute of Biotechnology (NIB) in Bangladesh, where he works within the Microbial Biotechnology Division. His research is primarily focused on the intersection of microbiology and genomics, with a strong emphasis on probiotics, antimicrobial resistance (AMR), and virology. Much of his recent work involves the pangenome analysis of probiotic strains like Weissella confusa and the exploration of secondary metabolites from soil and marine microbes for pharmaceutical applications. He has also made significant contributions to the genomic study of the Hepatitis B Virus (HBV) in the Bangladeshi population, specifically focusing on subgenotype C2 and its mutations. Additionally, his early research includes sustainable energy solutions, such as the generation of electricity from wastewater and sludge using Microbial Fuel Cells (MFCs). Mr. Hossain holds both a B.S. and an M.S. in Microbiology from the University of Dhaka, and his work continues to bridge traditional microbiological techniques with modern bioinformatics to address global health and food security challenges.
