Pro Tip: Choosing Your EEE PhD Topic Strategically
The most successful EEE PhD scholars in India choose topics at the intersection of two domains — for example, AI + Power Systems, IoT + Renewable Energy, or VLSI + Edge AI. Interdisciplinary topics tend to have broader journal scope, higher citation potential, and stronger funding eligibility. Cross-check your shortlisted topic against active SERB CRG, DST FIST, and IEEE TEMS call topics before finalising.
