Hlo dear, 

Firstly, if you are willing to continue your academics in this field you can apply for a Phd position in various universities within or outside India. Phd comes up with a very good stipend from the govt and thus helping the candidate to earn money while he is doing his research.

Secondly, you can join as a lecturer for +1, +2 courses and teach students. If you clear CSIR-NET lectureship then you will be able to get good salary during your teaching.

Third, you can join certain govt/private detective agencies for narcotics etc.,

Also, some of the pharmaceutical companies offer jobs in the respective positions in the production field.

Thank you. 

Good luck.
