Hi

Its good to know you are aspiring to go into research. There are several steps you could take next. You could either get enrolled in a basic sciences course eg. BSc in Biotech, or even pursue a technical degree like B.Tech. After this, you will have to choose a field in which you want to gain specialisation, and pursue a PhD in it. You would already be working on a research topic for the 4-5 years of your PhD duration, and you can always take that topic ahead or start working on a new one.

If you are really interested in research, I would suggest you to prepare for IISc or IISERs, they are the premier research institutes of the country.

Hope this helps!
