Dr. Sk Istiaque Ahmed earned his Ph.D. from The University of Tokyo, Japan, as a prestigious MEXT (Japanese Government Scholarship) scholar, recommended by the Embassy of Japan in Bangladesh. His doctoral research focused on marine fish distribution patterns and their relationships with biological, environmental, and oceanographic factors using Environmental DNA (eDNA)—a cutting-edge, non-invasive tool now widely applied in physical oceanography and open-water ecosystem studies. Through his innovative research, Dr. Ahmed demonstrated the suitability of the ship-bottom intake automated sampling technique for fish eDNA metabarcoding, offering a practical alternative to conventional sampling methods. This advancement is expected to enhance the understanding of global marine fish distribution and reduce the logistical challenges of traditional sampling for eDNA metabarcoding. During his Ph.D., he actively participated in 14 oceanographic research cruises and published several key scientific papers, establishing his expertise in marine biodiversity and eDNA-based ecological monitoring.
Currently, Dr. Ahmed serves as an Associate Professor in the Department of Fisheries Resource Management at Chattogram Veterinary and Animal Sciences University (CVASU). He is seeking collaborative opportunities in the fields of marine fish ecosystem management, species distribution modeling, and conservation research—with a vision to explore and document the understudied marine fish resources of Bangladesh and contribute to the nation’s marine economy and sustainable fisheries development.
Prior to joining CVASU, Dr. Ahmed completed his B.Sc. Fisheries (Honors) and M.S. in Fisheries Management with outstanding academic distinction from Bangladesh Agricultural University, Mymensingh. As an academician, Dr. Ahmed is deeply passionate about teaching contemporary topics in fisheries science, mentoring students, and guiding them through academic and real-life challenges with compassion and commitment.
