The Department of Microbiology has initiated two year Microbiology M.Sc. course on August 2010 and now has 10 faculty members representing different domains of Microbiology. Departmental students are usually involved in projects and present their papers in Indian Science Congress. The microbiology department conducts a two day seminar on Modern trends in Microbiology where the of 2nd year graduate students presents review papers. The field of microbiology is taken up by Dr. Arup Kumar Mitra, Ms. Debjani Dutta, Ms. Lopamudra Roy and Dr. Madhumita Maitra. The subject of Biochemistry is taken up by Dr. Sudeshna Shyam Choudhury, Dr. Kasturi Sarkar and Dr. Jaydeep Ghosh. Dr. Anindita Banerjee’s expertise lies in the field of plant tissue culture and plant physiology. The field of molecular biology is taken by Dr. Mahasweta Mitra Ghosh. The Biophysical part of the syllabus is taught by Dr. Jaydip Ghosh and Dr. Riddhi Majumder.

Thrust Areas:

Module based syllabus encompassing Microbiology, Biochemistry, Biophysics, Molecular Biology, Genetics, Instrumentation and Biostatistics.
