Dr. Mohamed Hatha is a distinguished marine microbiologist and was a professor at Cochin University of Science and Technology (CUSAT), where he led the Department of Marine Biology, Microbiology, and Biochemistry. His research focuses on the hidden microbial life in marine and coastal environments, particularly the diverse bacteria that influence ocean health. Dr. Hatha’s pioneering studies on foodborne pathogens in seafood, such as Salmonella, E. coli, and Vibrio species, explore their survival and drug resistance in natural habitats, shedding light on the complex relationship between human activities and marine ecosystems.

Bridging science and sustainability, Dr. Hatha has mobilized significant research funding to investigate the role of microbenthos—microscopic organisms living in ocean sediments—in regulating marine biogeochemical cycles. His work reveals how these tiny life forms contribute to the blue-green balance by cycling nutrients and supporting the health of aquatic habitats. With a background that spans from industry innovations in seafood safety to leading scientific expeditions in the Arctic, Dr. Hatha’s career exemplifies a commitment to protecting marine biodiversity and promoting sustainable ocean stewardship.

An acclaimed researcher and educator, Dr. Hatha has published over 100 papers and authored three books, translating marine microbial science into knowledge that can help safeguard our blue and green planet. His leadership in multidisciplinary projects and Arctic explorations underscores the global importance of microbes in oceans and their pivotal role in addressing environmental challenges like climate change and ocean pollution—core themes celebrated at Blue and Green LitFests worldwide.
