Jasna Vijayan
About Me
My self Dr Jasna Vijayan is a dedicated researcher and educator in the field of biological sciences, with particular expertise in microbiology, biotechnology, and environmental biology. My research focuses on microbial diversity, enzyme-producing bacteria, and the role of bacteria in aquaculture and environmental systems. He has contributed to studies on bacterial communities associated with microalgae and sediment microbiota in coastal ecosystems, with an emphasis on ecological functions and biotechnological applications.
In addition to this research, mine is passionate about teaching and mentoring students in the biosciences, and I am actively engages in promoting scientific literacy and research ethics. My work integrates field sampling, microbial isolation and characterization, and molecular techniques to address fundamental and applied questions in microbiology.
Work Experience
In CUSAT, as a part of UGC-Kothari post doctoral fellowship proposed study, Vibrio species and vibriophages are isolated from different aquatic environments and will be characterized using various techniques and tested against vibriosis infections as a preventive approach. Here I am adding research publications

As a part of my postdoc studies in Pukyong National university, am involved in investigating the connection between plankton and virus, especially viral hemorrhagic septicemia virus (VHSV) in seawater around fish farms in Korea. Since some plankton have already been reported as a vector for viruses based on these aspects sampling and quantification of VHSV in seawater through plankton sampling and microcosm studies of VHSV and plankton co-culture experiments. For identifying viruses from water sample and plankton sample is by viral concentration method and VHSV identification by real-time PCR methods. List of publications are listed here

Education & Training
My Ph.D. research focused on the distribution, dynamics, and diversity of viruses in the Cochin Estuary, a tropical monsoonal ecosystem in India. Through integrated field sampling, microscopy (EFM, TEM), microbial production assays, and metagenomic analysis, I uncovered significant spatial and seasonal variations in viral and prokaryotic abundance linked to salinity regimes and environmental parameters. The study demonstrated that viruses are critical in microbial mortality and carbon cycling, releasing substantial bacterial carbon and exhibiting distinct community compositions across salinity zones. This was the first comprehensive report on viral ecology from Indian estuarine waters, contributing new insights into viral morphotypes, host-virus interactions, and their functional roles in aquatic microbial loops. Building on this foundation. During my Ph.D. study, I published 6 international papers with a total impact factor of 22.331.
