Hey!

After your graduation in specific science-related field, you can apply for masters in the same field (or in some branch of that subject, depending on the choices different institutes proivde). You can pursue PhD afterwards to be fully inclined towards research.

You can apply for internships in different research institutes in your bachelors/masters for more research experience and for improving your CV.

As the years pass by, you will figure out the path you should choose. Always take guidance from your seniors and your professors for clarifications.

Best wishes!
