Biographic Sketch:
Working as an Associate Professor at the Department of Biotechnology, Central University of Tamil Nadu, Thiruvarur, India. Basically, he is an agricultural graduate, pursued M.Sc (Agri) in Plant Pathology as a ICAR-JRF at University of Agricultural Sciences, Bangalore. After clearing CSIR-JRF, he joined for his Ph.D in Biotechnology at Central Food Technological Research Institute (CSIR-CFTRI), Mysore. He has around 15 years of teaching and research experience from various state universities. His main area of research is plant genomics and metabolic regulation especially in oilseed plants through genetic engineering strategies. He isolated and functionally validated the high value polyunsaturated fatty acid (HVPUFA) genes like Eesaturase and Elongase from marine microalga and expressed in the heterologous system like E. coli. Also, engineered the model plant Arabidopsis thaliana and oilseed plants such as Soybean, Sesamum and Groundnut and regulated lipid biosynthetic pathway. He first described the Agrobacterium mediated genetic transformation in freshwater microalga Haematococcus pluvialis and regulated the carotenoid biosynthetic pathway for enhanced production of Astaxanthin a pigment. He has undergone several major research projects funded by UGC, DST, SERB, DBT and CSIR, Govt of India and published his findings in several peer reviewed international journals and book chapters in his credit.

   
Research Highlights :

Identified and characterized PUFA specific genes from marine microalgae and cloned the 5Des, 6Des and 6Elo genes and functionally characterized by expressing them in E.coli. Genetically engineered the model plant Arabidopsis thaliana and oilseed plants such as Soybean and Sesamum using these genes and regulated lipid biosynthetic pathway for HVPUFA production. First described the Agrobacterium mediated genetic transformation in freshwater green microalga – Haematococcus pluvialis and regulated the carotenoid biosynthesis for Astaxanthin production. Evaluated the PUFA enriched microalgal biomass to the animal model and proved the supplementation Isochrysis biomass to elevate eicosapentaenoicacid (EPA) and docosahexaenoicacid (DHA) in brain and other organs.
