Hi,

If you want to do research in the field of Chemistry, IISERs are one of the best options in the country. Some of the best ones for Chemistry are Mohali, Pune, Bhopal, Trivandrum etc though the other ones are also great. There are three channels to get admission there which are through KVPY, JEE Advanced and SCB(entrance called IAT). It is a great thing to get admission there and the best minds of the country can be found there.

All the best.
