PhD Admission - July 2012

Applications are invited for admission to the Doctor of Philosophy (Ph.D.) programme, starting in July 2012 in the following Departments. The areas of research in IIT Patna are as follows:

  • Computer Science and Engineering

  • Electrical Engineering

  • Mechanical Engineering

  • Chemistry

  • Mathematics

  • Physics

  • Humanities and Social Sciences

  • Inter-Disciplinary research

Category of Admission:

Regular and Full-Time

A student in this category works full-time for her/his PhD degree. They can be classified as

a) Institute Fellows
She/he receives assistantship from the Institute. The qualifying Degree for Financial Support is:

  • BE/ BTech/ MSc/ MA equivalent with valid GATE score above the prescribed cut off level/ NET /
    NBHM/ DBT-JRF qualification.
  • ME/ MTech or equivalent.

Age Limit: Please refer Eligibility Criteria for Admission into Ph.D. Programme

b) JRF/SRF Fellows
She/he receives fellowship from any Government recognized funding agencies, such as CSIR, UGC, DBT, etc.

Sponsored (Full -Time)

  • A student in this category is sponsored by a recognized R&D organization, academic institution, government organization or industry for doing research in the Institute on a full-time basis. The Institute does not provide any assistantship/fellowship to such a student.
  • Candidate in Sponsored category must be a regular employee of the sponsoring organization with at least one year of professional experience in the respective field.

Project Staff

This category refers to a student who is working on a sponsored project in the Institute and is admitted to the PhD Programme to work on a full-time or part-time basis. The remaining duration of the project at the time of admission should be at least two years. If the project gets completed before the student completes her/his PhD Programme, her/his category will be converted to that of SELF-FINANCED unless she/he is granted an assistantship/fellowship from the Institute or any other agency.
