Excellence and Relevance for Human Kind

Biotechnology - In Pursuit of Excellence and Relevance for Human Kind

The Department of Biotechnology is committed to generate excellence in biotechnology research for a strong, indigenous knowledge base and to ensure its application as a premier precision tool for creation of economic wealth for the welfare of the society and national prosperity. The last four decades represent the age of new Biology. Today biological sciences have become the harbinger of new and hitherto unimagined products and processes in the areas of food, feed, health, animal and plant productivity, environment conservation and energy generation. Sustainable development of our resources for ensuring food, nutritional, health, environmental and livelihood security of the people by harnessing the powers of biotechnology is a dream of the scientific community, being translated into products, processes and technologies. The focus during these two years has been on basic and application oriented new biology and biotechnology covering agriculture and plants, genomics, molecular medicine, bioinstrumentation, bioinformatics, biofuels, biofertilizers, biopesticides, human resource development and environment and biodiversity. The Department has developed biosafety protocols and guidelines related to ethical issues. Partnership with the industry for commercialization of technology and marketing of bioproducts is another area where there has been some success. A major pursuit thus has been to bring synergy between researchers, academicians, industry, policy makers and public. Vision - Biotechnology -A Ten Year Perspective On September 7, 2001, Hon'ble Prime Minister, Shri Atal Bihari Vajpayee released the 'Biotechnology - A Vision - Ten Year Perspective' document of the department.
