What is phd?
A PhD (Doctor of Philosophy) is the highest academic degree you can earn. It shows you have become an expert in a specific field by doing original research and writing a detailed report called a dissertation.
Let's break it down
- Study length: Usually 3‑6 years after a master’s degree.
- Research focus: You pick a narrow topic, investigate it deeply, and try to discover something new.
- Dissertation: A long written document that explains your research methods, findings, and why they matter.
- Defense: You present your work to a panel of experts who ask questions before awarding the degree.
