Eligibility Criteria

Master's degree in engineering in relevant field with 60 % marks or equivalent CPI/CGPA.

OR

Bachelor's degree in engineering in relevant field (typically 4-year Programme) with a minimum of 90 % marks or equivalent CPI/CGPA and a valid GATE score of 99 percentile or above in the relevant area of application (e.g. For Ph.D. in CSE, a B.Tech(CSE) with indicated percentage or CPI/CGPA and a valid GATE score in Computer Science and Information Technology(CS) ).

The students awaiting their qualifying examination results are also eligible to apply. They need to submit the qualifying mark sheets and/or certificates at the time of admission.

Please note that the qualifying degree of applicant should be from an accredited university /deemed-to-be-university or an institution of higher learning of comparable standing. The eligibility criteria given above are the absolute minimum. Institute may prescribe any requirements over and above these. In case the candidates are awarded grades/CPI/CGPA instead of marks, applicant would have to produce the grade-percentage conversion criterion or formula provided by the university/institution from where the applicant has obtained the degree. In case, where, a university/institute does not provide any scheme for converting CPI/CGPA into equivalent marks, UGC and AICTE guidelines would be applicable.

Admission Procedure

Admission to the Ph.D. Programme is offered to eligible candidates on the basis of an entrance examination and an interview. Consequently, all applicants who qualify in the written examination have to appear for the personal interview on the same day or very next day. Candidates who have qualified for national level fellowships like CSIR/UGC-NET-JRF, DST-INSPIRE, NBHM Ph.D. scholarship or equivalent valid fellowship in the relevant subject/discipline may be exempted from the written examination but not from the interview. No request for remote interviews would be entertained.
