    • "Indian Institute of Science Education and Research Kolkata (IISER Kolkata) was established in 2006 by the Ministry of Human Resource Development (MHRD), Government of India. IISER Kolkata is designed to reach the prestigious position in the global setting that IISc, IIMs and IITs presently enjoy. IISER Kolkata is an autonomous institution awarding its own degrees. The central theme of the IISER Kolkata is to integrate education with research so that undergraduate teaching as well as doctoral and postdoctoral research work could be carried out in symbiosis."

      About IISER Kolkata
    • "The Department of Biological Sciences at IISER Kolkata integrates cutting edge research with innovative teaching at undergraduate and post-graduate levels, constantly striving towards academic and scientific excellence. Since its inception in 2006, the department has made its mark in biology research and teaching in India. Focusing on the essential unity among biological systems, research in the department spans from the molecular to the organismal levels."

      About Department of Biological Sciences
    • "Research and teaching in the Department of Biological Sciences is supported by state of the art instruments and facilities such as confocal microscopy, flow cytometry, histopathology, tissue culture and facilities for housing and conducting research on various organisms. These are maintained as departmental and institutional facilities, providing easy accessibility to all investigators and allowing collaborative and interdisciplinary research to flourish in the department."
