What is the key difference between a problem statement and research gap for PhD research‑ While starting research, do we first find research gaps or find research problems or does it mean the same thing?
When starting my doctoral journey, I find these two concepts are often conflated in guides and discussions. My confusion is practical: do I look for a real-world problem first, or do I dive into the literature to find a gap? Understanding their relationship would help me structure my early thinking correctly.

Think of it this way: the problem statement is often a broader, real-world or theoretical issue (e.g., "a high failure rate in engineering bridges"). The research gap is the specific lack of scholarly knowledge that prevents us from solving that problem (e.g., "no studies have applied Material X in cold-weather stress tests"). You often start with a broad problem area, then through literature review, you drill down to pinpoint the exact gap. They are not the same; the gap is a subset of the problem. I recommend starting with a practical problem, then letting the literature reveal the precise academic gap your thesis can address.
