IIST Ph.D. Physics Scholarships 2026

IIST provides generous financial support to Ph.D. scholars, making the programme financially self-sustaining for most students. All institute-funded scholars receive a monthly fellowship that covers living expenses, and additional support is available through external government funding agencies. The fellowship structure is aligned with national standards set by CSIR and UGC.

Fellowship Details

Scholarship / Fellowship	Amount	Duration	Eligibility
Junior Research Fellowship (JRF) - IIST	Rs. 37,000 per month	Up to 2 years	All IIST-funded Ph.D. scholars
Senior Research Fellowship (SRF) - IIST	Rs. 42,000 per month	Up to 3 additional years (max 5 years total)	After successful performance review at 2 years
CSIR-JRF / UGC-JRF	As per agency norms (Rs. 37,000/month)	As per agency rules	Scholars with valid CSIR/UGC-NET-JRF award
NBHM Fellowship	As per NBHM norms	As per agency rules	Scholars with valid NBHM award
DST / State Govt. Science & Technology Scheme	As per agency norms	As per agency rules	Scholars with valid fellowship from respective agency
HRA (House Rent Allowance)	As per institute norms	Duration of programme	Scholars staying outside campus (hostel not availed)

Scholars receiving fellowship from external agencies (CSIR, UGC, DST, NBHM, State Govt.) draw their fellowship directly from those organizations; IIST does not bear the fellowship in such cases.
If an external fellowship is discontinued by the funding agency for any reason, IIST will not bear the fellowship amount.
Travel grants are available for scholars to attend national and international conferences.
No separate scholarship application is required for IIST fellowship; it is automatically awarded upon admission to the institute-funded programme.

IIST Ph.D. Physics FAQs

Ques. Does IIST Ph.D. Physics require GATE, or is JEST/CSIR-NET sufficient?

Ans. For the Physics department, IIST accepts CSIR/UGC-NET (Physical Sciences), JEST (Physics), GATE (Physics), and NBHM as qualifying national eligibility tests. Candidates with a valid score in any of these are eligible for Direct Interview. Those without any of these scores can still apply and appear for IIST's own Screening Test followed by an Interview. However, for certain research areas in Physics (such as Experimental Quantum Optics), IIST specifically requires UGC-CSIR NET (Physics), JEST, or a valid GATE score in Physics even for engineering graduates.

Ques. Is the Ph.D. at IIST fully funded? Do scholars have to pay fees from their fellowship?

Ans. Yes, IIST-funded scholars receive a JRF of Rs. 37,000 per month, which is more than sufficient to cover the semester fees (approximately Rs. 17,700 per semester from the 2nd semester onwards, including hostel). The fellowship effectively makes the programme self-funded for most scholars. SC/ST/PwD students are additionally exempted from tuition fees.

Ques. How many seats are available for Ph.D. Physics at IIST per cycle?

Ans. The number of seats varies each cycle depending on faculty availability and research funding. For the July 2025 cycle, the Physics department offered 3 research areas (Experimental Quantum Optics, Fundamental and Applied Optics, and Atomic and Molecular Physics) under IIST funding. The exact seat count per area is determined by the institute and announced in the official notification. Typically, 1-2 seats are available per research area per session.

Ques. Can I apply for Ph.D. Physics at IIST if I have a B.Tech in Engineering Physics?

Ans. Yes. Candidates with a B.Tech in Engineering Physics (or equivalent) are eligible to apply for Ph.D. Physics at IIST, provided they have a valid GATE score in Physics or have qualified CSIR/UGC-NET/JEST/NBHM. B.Tech graduates admitted to the Ph.D. programme are required to complete additional coursework as prescribed by the institute.

Ques. What is the research focus of the Physics department at IIST, and how is it connected to ISRO?

Ans. The Physics department at IIST focuses on Quantum Optics and Quantum Technologies, Solid State Physics, Statistical Physics and Nonlinear Dynamics, Atomic and Molecular Physics, and Applied and Adaptive Optics. The department is actively building a Centre for Excellence in Quantum Technologies. Being a Deemed University under the Department of Space (DOS), IIST scholars have access to ISRO facilities and collaborative research opportunities with ISRO scientists, which is a unique advantage not available at most other universities.

Ques. Is hostel accommodation guaranteed for Ph.D. Physics scholars at IIST?

Ans. Hostel accommodation is available on campus but is subject to availability. Preference is given to scholars whose fellowships are borne by IIST (institute-funded scholars). Scholars who do not get hostel accommodation are provided House Rent Allowance (HRA) as per institute norms. Canteen/mess facility is available on a payment basis at approximately Rs. 3,000 per month.
