About Post Doctoral Fellowship Programme
The Post-Doctoral Fellowship (PDF) / Research Associate (RA) Programme at the Indian Institute of Space Science and Technology (IIST), Thiruvananthapuram is a full-time, campus-based research programme open to PhD degree holders across a broad range of disciplines including Science, Engineering, Humanities, Social Sciences, and Management.
