Dear Student,

The duration of PhD program in Mathematical Sciences at National Institute of Science Education & Research (NISER), Bhubaneswar is typically 3 to 5 years. The total fees for the entire duration range from INR 70,000 to INR 88,000. This cost is significantly offset by a monthly fellowship: As a Junior Research Fellow (JRF), you receive INR 37,000 for the first two years, which later goes up to INR 42,000 for a Senior Research Fellow (SRF) for the remaining period. 

We hope this answers your query. If you have further queries regarding college/ course admission, you can write to …
