About DBT’s Star College Scheme

The Star College scheme by the Department of Biotechnology of the Government of India facilitates improvement in the skills of teachers through FDPs, improved curriculum, and practical training to the students by providing specialised access to infrastructure and consumables. The support provided under the scheme strengthens physical infrastructure in laboratories, library, teaching aids and promotes networking with neighbouring institutes. Hands on training, product oriented projects and projects of day to day relevance enhance the interest in students to pursue science at undergraduate level.

PSGRKCW in Star College scheme

Basic Science departments – Physics , Chemistry, Botany, Zoology and Mathematics – of PSGRKCW were selected under DBT Star scheme in 2012 under category I – strengthening of support for undergraduate education. Three more departments – Computer Science, Computer Applications and Information Technology were also included under the strengthening component in 2016. Based on the performance and the progress made by these departments, they were evaluated and upgraded to category II Star status in 2017 (Basic Sciences) and 2019 (Computer Science Departments).


PSGR Krishnammal College for Women has been sanctioned with a grant of Rs.1.2 crores to establish DBT-BUILDER – PSGR Krishnammal College for Women - Interdisciplinary Life Science Programme for Advance Research and Education under the “Boost to University Interdisciplinary Life science Departments for Education and Research (BUILDER – Level-1)” Programme for advanced research and education by the Department of Biotechnology (DBT) Ministry of Science and Technology, Government of India. BUILDER programme aims to promote interaction of existing life science departments in interdisciplinary research through creation of new research agenda.

Objectives of the programme are to

  • Upgrade, modernise life science laboratories – teaching learning,research and skill enhancement training
  • Augment inter-disciplinary bioscience core research through inter-departmental and inter-institutional collaboration.
  • Extend innovative research in Biotechnology (from discovery to market)through re- grouping research activities and training programmes
  • Increase the number of postgraduate students at M.Sc., Ph.D., and Postdoctoral levels with quality education, skills and research temperament is envisaged.
  • Bridge the gap between Academia and Industry resulting in public-private partnership to establish interdisciplinary and trans-disciplinary advanced Education and research
  • Create and promote young Bio-entrepreneurs with meaningful contributions towards bioeconomy
