Profile
Dr Ramu S Vemanna is an Associate Professor at the Regional Centre for Biotechnology. He is an expert in Plant Molecular biology and Genetic Engineering. He received his PhD from the Department of Biotechnology, Bangalore University in 2013. After his doctoral studies, he moved to the Noble Research Institute, Oklahoma, USA, on a Fulbright- Nehru postdoctoral fellowship assignment. Dr. Ramu has vast experience in many areas of plant biology. He did his doctoral program on insect resistance transgenic plants and postdoctoral training on plant pathology and had a sound publication track on the abiotic stress tolerance of crops. He has experience in multigene engineering to improve plant abiotic and biotic stress tolerance mechanisms. At RCB, his group is working on genome editing aspects and developing new methods to enhance plant drought stress tolerance. His group focuses on the functional characterisation of genes associated with translation mechanisms.
Current Focus Areas
Protein translational mechanisms in plants, Extra-ribosomal functions of ribosomal proteins, Ribosome biogenesis factors in plant growth and development. Regulatory proteins of ribosome biogenesis. Drought stress adaptation of plants.
