PhD Advertisement for Autmn Semester 2023 (DPS)

Special PhD interviews only for candidates qualifying the NET-JRF fellowship in July 2023 for the Autumn 2023 semester

**Minimum Eligibility criteria:**

**Candidates must obtain the NET-JRF fellowship in July 2023.**

Applications are invited from candidates having Masters degree with at least 60% aggregate marks in any field of Physical Sciences for the Doctor of Philosophy (PhD) program. Final year post-graduate students who are yet to obtain their degree may also apply, however, they must complete the MSc/MS degree at the time of admission with the requisite 60% aggregate marks.

Selection of the candidates will be as per the GoI norms. Candidates belonging to the respective reserved category need to submit relevant certificates and documents.
