The Faculty is starting a competitive and vibrant Ph.D program for students who possess M.Sc or M.Tech degree from July 2013.

Students enrolled in the Ph.D program can work in the following cutting edge areas of Biotechnology.

1. Immunology

2. Virology

3. Molecular Medicine

4. Neuroscience

5. Drosophila Genetics

6. Protein Engineering

7. Chemical Biology

8. Structural Biology

9. Cancer Biology

10. Plant Molecular Biology

11. Applied and Industrial Biotechnology

Admission to the program will be through a common entrance exam held in all the SAARC countries followed by an interview.

Course Work

Assigned Pre-Ph.D. / MPhil course work will be carried out over first two semesters and will carry 16 credits including credits for course work (14 credits), seminar and term papers (1 credit each).

At the end of first year candidates with CGPA less than 5.5 will be deemed to have failed and shall leave the university. No re-tests will be permitted.

Candidates with CGPA of 6.5 and above will be offered direct confirmation to Ph.D. programme. Candidates with CGPA between 5 to less than 6.5 will go to MPhil stream and carry out a one-year thesis work (8 Credits). After completion of MPhil, students with total MPhil CGPA of 6.5 or more will be allowed to register for PhD programme. Candidates with MPhil CGPA of 5 to less than 6.5 will leave the university with an MPhil degree.

Part A – will contain 20 questions carrying one mark each. The paper will be of B.Sc. level. This Part will have questions from all branches of Biology. Candidates will be expected to attempt all questions from Part-A.

Part B – This part will contain total of 100 questions out of which the candidates will have to answer any 50 questions. Part-B will have M.Sc. level questions from the subjects of Biochemistry, Cell Biology, Molecular Biology, Immunology, Plant and animal Sciences, Genetics, Microbiology, Biophysics and Bioinformatics.

Interview: Candidates upto four times the number of seats will be short-listed for interview on the basis of their performance in entrance test subject to a minimum cut off. The candidate will also arrange to send two recommendation letters from teachers who have taught and assessed the candidate during graduate/postgraduate studies. Recommendation letters should testify to the intellectual acumen, knowledge of the subject and ability of the candidate to articulateideas. Interview will carry 30 marks. Candidates from outside India will be interviewed through Skype.

A final merit list will be drawn by adding marks of the entrance test and the interview. Separate merit lists will be made for (a) candidates from all SAARC countries other than India, and (b) candidates from India. Equal number of candidates will be offered admission from these two lists, provided they secure overall qualifying marks of minimum 50.
