Is it possible to do research after completing Diploma in ECE? How can I do that if it's possible?

Dea Ravi, After diploma engineering, you can fill the form of DRDO. Every year, DRDO conducts it's own exam I.e CEPTAM to recruit students for the job where you can do research. It's a great idea but for that, you will have to work hard. Do more study and more preparation to get select in DRDO.
