Attaining the B.S-M.S programme of IISER will turn out to be quite effective for carrying an astronomy-related career, primarily provided followed by doing a PhD in a similar programs. For doing a sound education consisting of theoretical principles at high intensity along with experimental research inputs on the platform is required if advancing into study with astrophysics-related domains. The students graduating from IISER tend to continue in Ph.D. programs, not only in India but also abroad. Strong research foundations and networking help them do this. So, most alumni find positions as research scientists, academics, or industry professionals associated with physics and astronomy-related sectors.

The choice of going to IITs and IIMs would depend on the type of goals and focus area your research is targeting to go for a Ph.D. in Economics:

1. IITs- Indian Institutes of Technology They mainly have technical and engineering-centric disciplines but also strong, high-quality Ph.D. programs in Economics, especially under the Humanities and Social Sciences departments. IITs like IIT Bombay and IIT Delhi are interdisciplinary, bringing together economics in combination with quantitative techniques and computational ones. With an interest in applied economics, a focus of econometrics, or data analysis work, IITs provide all that with the research-intensive environment, with technology being an added impetus supported by innovation Institutes of Management): IIMs like IIM Ahmedabad, IIM Bangalore, and IIM Calcutta will have specialised Ph.D.s in Economics, which include departments for economics and business policy.
