Hailing from a coastal village near the historical town of Chidambaram, in South India, Professor Jayaraj Jayaraman graduated in Agriculture, earning a doctoral degree in Plant Pathology from Annamalai University, India. He served as a Senior lecturer at Annamalai University till 1999. He was a DST-BOYSCAST visiting scientist at Kansas State University (KSU), USA, where he completed his postdoctoral training up to 2000. He served at KSU as Associate Scientist up to 2003 and later as Senior Scientist at Simon Fraser University, Canada between 2003 and 2009. He joined the UWI-St. Augustine and was serving as a Senior Lecturer in Microbiology and Biotechnology. In 2014, he was installed as a full Professor of Biotechnology and Plant-Microbiology at the Dept. of Life Sciences, UWI-St. Augustine.
His research area spans the fields of sustainable agriculture, plant pathology, plant microbiology, and biotechnology. He chairs the Biotechnology program at the UWI-St. Augustine. He has completed more than 25 funded research projects and published more than 130 refereed publications. His group recently received a patent for the development of a novel antibiotic adjuvant.
He has received several awards including the UNDP-CARUTA Research Award; The UWI- Vice-Chancellor's Excellence Award for Outstanding Research Accomplishments; ACTT Award - Govt. of T&T for Outstanding Achievements in Applied and Academic Research and the Environmental Management Authority-T&T- Greenleaf Award. He is a DST-BOYSCAST Fellow, an elected Fellow of the Indian Phytopathological Society, and an elected UNESCO-TWAS Fellow of Agriculture Science. He served as the advisor to the UNU-BIOLAC program of the UN. He serves as a plant protection advisor to programs for several Caribbean states. region. His research projects cover diverse topics focusing IDM/IPM methods, biological control, molecular-based disease diagnostics, plant-microbe interactions, elicitor-biomolecules, induced disease resistance, seaweed products for agriculture and health, genetic engineering of plants for biotic stress tolerance and identification of novel biomolecules for potential drug-value.
