A doctorate or a Ph.D. in Computer Science, is a programme that emphasises advanced research and academic study in the field of computer science. It is the highest degree of education one can receive in the field and is often pursued by those who want to work as scientists, educators, or experts in particular branches of computer science.
The Ph.D. programme typically lasts several years, during which time students immerse themselves in diligent academic study, help contribute to the computer science field, and develop the critical thinking, problem-solving, and research skills necessary to succeed in academia, industry, or both.
